Andrey Ryabinin 4f24ecff01 platform/x86: intel_pmc_core: fix out-of-bounds accesses on stack
pmc_core_mtpmc_link_status() an pmc_core_check_read_lock_bit() use
test_bit() on local 32-bit variable. This causes out-of-bounds
access since test_bit() expects object at least of 'unsigned long' size:

Hans de Goede cef9dd85ac platform/x86: add support for devices with Silead touchscreens
On ACPI based tablets, the ACPI touchscreen node only contains info on
the gpio and the irq, and is missing any info on the axis. This info is
expected to be built into the tablet model specific version of the driver
shipped with the os-image for the device.

Add support for getting the missing info from a table built into the
driver, using dmi data to identify which entry of the table to use and
add info for the CUBE iwork8 Air and Jumper EZpad mini3 tablets on which
this code was tested / developed.

Srinivas Pandruvada 4ec567b8dd platform/x86: Support Turbo Boost Max 3.0 for non HWP systems
On platforms supporting Intel Turbo Boost Max Technology 3.0, the
maximum turbo frequencies (turbo ratio) of some cores in a CPU package
may be higher than the other cores in the same package.  In that case,
better performance can be achieved by making the scheduler prefer to run
tasks on the CPUs with higher max turbo frequencies.

On Intel® Broadwell Xeon systems, it is optional to turn on HWP
(Hardware P-States). When HWP is not turned on, the BIOS doesn't
present required CPPC (Collaborative Processor Performance Control)
tables. This table is used to get the per CPU core maximum performance
ratio and inform scheduler (in cpufreq/intel_pstate driver).

On such systems the maximum performance ratio can be read via over
clocking (OC) mailbox interface for each CPU. This interface is not
architectural and can change for every model of processors.

This driver reads maximum performance ratio of each CPU and set up
the scheduler priority metrics. In this way scheduler can prefer CPU
with higher performance to schedule tasks.

Dell-smbios is a helper module, it serves no purpose on its own, so
do not present it as an option to the user. Instead, select it

Also select DCDBAS as needed, instead of depending on it, so that
the Dell driver options are always visible.

As a clean-up, I removed the "default n" statements as they are not

But then commit 634830704d ("x86/mid/thermal: Add msic_thermal alias")
changed DRIVER_NAME from "msic_sensor" to "msic_thermal", and so there's

The SoC supports up to 6 clocks (PMC_PLT_CLK[0..5]) with a
frequency of either 19.2 MHz (PLL) or 25 MHz (XTAL) for BayTrail
and a frequency of 19.2 MHz (XTAL) for CherryTrail. These clocks
are available for general system use, where appropriate. For example,
the usage for platform clocks suggested in the datasheet is the
following:
  PLT_CLK[0..2] - Camera
  PLT_CLK[3] - Audio Codec
  PLT_CLK[4] -

ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

Benjamin Tissoires 1a64b719d3 platform/x86: Introduce button support for the Surface 3
The Surface 3 is not following the ACPI spec for PNP0C40, but nearly.
The device is connected to a I2C device that might have some magic
but we don't know about.
Just create the device after the enumeration and use the declared GPIOs
to provide button support.

This driver is just an adaptation of drivers/input/misc/soc_button_array.c

The Surface Pro 3 is using an ACPI driver and matches against the bid
of the device ("VGBI"). To prevent this incompatible driver to be used
on the Surface Pro, we add a match on the Surface 3 bid "TEV2".

Benjamin Tissoires 3dda3b3798 platform/x86: Add custom surface3 platform device for controlling LID
The LID state provided by ACPI on the Surface 3 is not accurate.
The ACPI node doesn't get notified on LID open, which means the
LID input switch stays close most of the time.

Fortunatelly, there is a WMI method which directly queries the
GPIO underneath the LID state, so it's far more reliable than ACPI.
To get the notifications that the LID was opened/closed, we can
rely on the ACPI notification of the touchscreen: the DSDT shows
that the touchscreen will get notified on close/open as it also
controls its _STA method.

Note that we need to set the tag "power-switch" to the LID
input node through a udev rule for logind to accept it:

SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \
	TAG+="power-switch"

Lyude b318002838 platform/x86: thinkpad_acpi: Move tablet detection into separate function
The hotkey events and ACPI handles used for detecting tablet mode on a
few of the newer thinkpad models (Yoga X1 and the Yoga 260 specifically)
have been changed around, so unfortunately this means we're definitely
going to need to probe for multiple types of tablet mode support. Since
the hotkey_init() is already a lot larger than it should be, let's split
up this detection into its own function to make things a little easier
to read.

As well, since we're going to have multiple types of tablet modes, make
hotkey_tablet into an enum so we can also use it to indicate the type of
tablet mode reporting the machine supports.

By referencing Intel Platform Controller Hub(PCH) datasheet,
the xHC USB 2.0 Port Routing(XUSB2PR) at offset 0xD0-0xD3h
decides the setting of mapping the port to EHCI controller or
xHC controller. And the port mapped to xHC will enable xHCI
during bus resume.

The setting of disabling bluetooth adapter's connected port is
0x000001D9. The value can be obtained by few times 1 bit flip
operation. The suited configuration should have the 'lsusb -t'
result with bluetooth using ehci:

Rajneesh Bhardwaj 173943b3da platform/x86: intel_pmc_core: ModPhy core lanes pg status
The PCH implements a number of High Speed I/O (HSIO) lanes that are split
between PCIe*, USB 3.0, SATA, GbE, USB OTG and SSIC. This patch shows the
current power gating status of the available ModPhy Core lanes. This is
done by sending a message to the PMC (MTPMC) that contains the XRAM
register offset for the MPHY_CORE_STS_0 and MPHY_CORE_STS_1 and then by
reading the response sent by the PMC (MFPMC).

While enabling low power modes we often encounter situations when the
ModPhy lanes are not power gated and it becomes hard to debug which lane is
active and which is not in the absence of an external hardware debugger
(JTAG/ITP). This patch eliminates the dependency on an external hardware
debugger for reading the ModPhy Lanes power gating status.

This patch requires PMC_READ_DISABLE setting to be disabled in the platform
bios.

Rajneesh Bhardwaj 0bdfaf429d platform/x86: intel_pmc_core: Add PCH IP Power Gating Status
This patch adds the support for reading the power gating status of various
devices present on Sunrise Point PCH. This is intended to be used for
debugging purpose while tuning the platform for power optimizations and
also to understand which devices (on PCH) are blocking the system to enter
a low power state.

Power Management Controller on Sunrise Point PCH provides access to "PGD
PFET Enable Ack Status Registers (ppfear)". This patch reads and decodes
this register and dumps the output in formatted manner showing various
devices present on the PCH and their "Power Gating" status.

Further documentation can be found in Intel 7th Gen Core family mobile u/y
processor io datasheet volume 2.

The AMW0_GUID1 wmi is not only found on Acer family but also other
machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled
those non-Acer machines by quirks list.

But actually acer-wmi driver was loaded on any machine that had
AMW0_GUID1. This behavior is strange because those machines should be
supported by appropriate wmi drivers. e.g. fujitsu-laptop,
ideapad-laptop.

This patch adds the logic to check the machine that has AMW0_GUID1
should be in Acer/Packard Bell/Gateway white list. But, it still keeps
the quirk list of those supported non-acer machines for backward
compatibility.

that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.

To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

   the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
   msm8916, msm8960, msm8974 and msm8996 families is also added. From
   Rajendra Nayak

 - Introduce hardware-tracked trip points support to the device tree
   thermal sensor framework. The framework supports an arbitrary number
   of trip points. Whenever the current temperature is changed, the trip
   points immediately below and above the current temperature are found,
   driver callback is invoked to program the hardware to get notified
   when either of the two trip points are triggered. Hardware-tracked
   trip points support for rockchip thermal driver is also added at the
   same time. From Sascha Hauer, Caesar Wang

Arnd Bergmann 127595ed21 platform/x86: intel_pmc_core: avoid boot time warning for !CONFIG_DEBUGFS_FS
While looking at a patch that introduced a compile-time warning
"‘pmc_core_dev_state_get’ defined but not used" (I sent a patch
for debugfs to fix it), I noticed that the same patch caused
it in intel_pmc_core also introduced a bogus run-time warning:
"PMC Core: debugfs register failed".

The problem is the IS_ERR_OR_NULL() check that as usual gets
things wrong: when CONFIG_DEBUGFS_FS is disabled,
debugfs_create_dir() fails with an error code, and we don't
need to warn about it, unlike the case in which it returns
NULL.

This reverts the driver to the previous state of not warning
about CONFIG_DEBUGFS_FS being disabled. I chose not to
restore the driver to making a runtime error in debugfs
fatal in pmc_core_probe().

ACPI WDAT table is the preferred way to use hardware watchdog over the

Prevent iTCO watchdog creation if we detect that there is an ACPI WDAT

Oleksij Rempel b5643539b8 platform/x86: asus-wmi: Filter buggy scan codes on ASUS Q500A
Some revisions of the ASUS Q500A series have a keyboard related
issue which is reproducible only after Windows with installed ASUS
tools is started.

In this case the Linux side will have a blocked keyboard or
report incorrect or incomplete hotkey events.

To make Linux work properly again, a complete power down
(unplug power supply and remove battery) is needed.

Linux/atkbd after a clean start will get the following code on VOLUME_UP
key: {0xe0, 0x30, 0xe0, 0xb0}. After Windows, the same key will generate
this codes: {0xe1, 0x23, 0xe0, 0x30, 0xe0, 0xb0}. As result atkdb will
be confused by buggy codes.

This patch is filtering this buggy code out.

Giedrius Statkevičius 6f7e357bf1 platform/x86: asus-laptop: get rid of parse_arg()
parse_arg() duplicates the funcionality of kstrtoint() so use the latter
function instead. There is no funcionality change except that in the
case of input being too big -ERANGE will be returned instead of -EINVAL
which is not bad because -ERANGE makes more sense here. The check for
!count is already done by the sysfs core so no need to duplicate it
again. Also, add some minor corrections to error handling to accommodate
the change in return values (parse_arg returned count if everything
succeeded whereas kstrtoint returns 0 in the same situation)

The Kconfig entry controlling compilation of this code is:

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

We delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

João Paulo Rechi Vita a977e59c0c asus-wmi: Create quirk for airplane_mode LED
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:

Scope (_SB)
{
  (...)
  Device (ATKD)
  {
    (...)
    Method (WMNB, 3, Serialized)
    {
      (...)
      If (LEqual (IIA0, 0x00010002))
      {
        OWGD (IIA1)
        Return (One)
      }
    }
  }
}

So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.

This commit creates a quirk to not register a RFKill switch at all for
these laptops, to allow the asus-wireless driver to drive the airplane
mode LED correctly through the ASHS ACPI device. It also adds a match to
that quirk for the Asus X555UB, which is affected by this problem.

João Paulo Rechi Vita 2c1a49c961 asus-wireless: Toggle airplane mode LED
In the ASHS device we have the HSWC method, which calls either OWGD or
OWGS, depending on its parameter:

	Device (ASHS)
	{
		Name (_HID, "ATK4002")  // _HID: Hardware ID
		Method (HSWC, 1, Serialized)
		{
			If ((Arg0 < 0x02))
			{
				OWGD (Arg0)
				Return (One)
			}
			If ((Arg0 == 0x02))
			{
				Local0 = OWGS ()
				If (Local0)
				{
					Return (0x05)
				}
				Else
				{
					Return (0x04)
				}
			}
			If ((Arg0 == 0x03))
			{
				Return (0xFF)
			}
			If ((Arg0 == 0x04))
			{
				OWGD (Zero)
				Return (One)
			}
			If ((Arg0 == 0x05))
			{
				OWGD (One)
				Return (One)
			}
			If ((Arg0 == 0x80))
			{
				Return (One)
			}
		}
		Method (_STA, 0, NotSerialized)  // _STA: Status
		{
			If ((MSOS () >= OSW8))
			{
				Return (0x0F)
			}
			Else
			{
				Return (Zero)
			}
		}
	}

On the Asus laptops that do not have an airplane mode LED, OWGD has an
empty implementation and OWGS simply returns 0. On the ones that have an
airplane mode LED these methods have the following implementation:

	Method (OWGD, 1, Serialized)
	{
		SGPL (0x0203000F, Arg0)
		SGPL (0x0203000F, Arg0)
	}

	Method (OWGS, 0, Serialized)
	{
		Store (RGPL (0x0203000F), Local0)
		Return (Local0)
	}

Where OWGD(1) sets the airplane mode LED ON, OWGD(0) set it off, and
OWGS() returns its state.

This commit exposes the airplane mode indicator LED to userspace under
the name asus-wireless::airplane, so it can be driven according to
userspace's policy.

Michał Kępień 1879e69f4c fujitsu-laptop: Support touchpad toggle hotkey on Skylake-based models
Haswell-based Fujitsu laptops (Lifebook E734/E744/E754) have a touchpad
toggle hotkey (Fn+F4) which is handled transparently to the operating
system: while an ACPI notification is sent to FUJ02B1 when Fn+F4 is
pressed, touchpad state is properly toggled without any explicit support
for this operation in fujitsu-laptop.

Skylake-based models (Lifebook E736/E746/E756) also have that hotkey,
but the touchpad is not toggled transparently to the operating system.
When Fn+F4 is pressed, an ACPI notification is sent to FUJ02E3.  A
subsequent call to S000 (FUNC_RFKILL) can be used to determine whether
the touchpad toggle hotkey was pressed so that an input event can be
sent to userspace.

Relevant ACPI code:

    Method (_L21, 0, NotSerialized)
    {
        ...
        If (AHKF)
        {
            Notify (\_SB.FEXT, 0x80)
        }
        ...
    }

    Method (S000, 3, Serialized)
    {
        Name (_T_0, Zero)
        Local0 = Zero
        While (One)
        {
            _T_0 = Arg0
            If (_T_0 == Zero)
            {
                Local0 |= 0x04000000
                Local0 |= 0x02000000
                Local0 |= 0x00020000
                Local0 |= 0x0200
                Local0 |= 0x0100
                Local0 |= 0x20
            }
            ElseIf (_T_0 == One)
            {
                ...
                If (AHKF & 0x08)
                {
                Local0 |= 0x04000000
                AHKF ^= 0x08
                }
                ...
            } ...
            Break
        }
        Return (Local0)
    }

Pressing Fn+F4 raises GPE 0x21 and sets bit 3 in AHKF.  This in turn
results in bit 26 being set in the value returned by FUNC_RFKILL called
with 1 as its first argument.  On Skylake-based models, bit 26 is also
set in the value returned by FUNC_RFKILL called with 0 as its first
argument (this value is saved in fujitsu_hotkey->rfkill_supported upon
module initialization), which suggests that this bit is set on models
which do not handle touchpad toggling transparently to the operating
system.

Note that bit 3 is cleared in AHKF once FUNC_RFKILL is called with 1 as
its first argument, which requires fujitsu-laptop to handle this hotkey
in a different manner than the other, GIRB-based hotkeys: two input
events (press and release) are immediately sent once Fn+F4 is pressed.

Pali Rohár e075b3c898 dell-wmi: Generate one sparse keymap for all machines
This patch reworks code for generating sparse keymap and processing WMI
events. It unifies procedure for generating sparse keymap and also unifies
big switch code for processing WMI events of different types. After this
patch dell-wmi driver does not differ between "old" and "new" hotkey type.

It constructs sparse keymap table with all WMI codes. It is because on some
laptops (e.g. Dell Latitude E6440) ACPI/firmware send both event types (old
and new).

Each WMI code in sparse keymap table is prefixed by 16bit event type, so it
does not change functionality on laptops with "old" hotkey support (those
without scancodes in DMI).

This allow us to distinguish between same WMI codes with different types in
sparse keymap. Thanks to this WMI events of type 0x0011 were moved from big
switch into sparse keymap table too.

This patch also fixes possible bug in parsing WMI event buffer introduced
in commit 5ea2559726 ("dell-wmi: Add support for new Dell systems"). That
commit changed buffer type from int* to u16* without fixing code. More at:

Rajneesh Bhardwaj b740d2e923 platform/x86: Add PMC Driver for Intel Core SoC
This patch adds the Power Management Controller driver as a PCI driver
for Intel Core SoC architecture.

This driver can utilize debugging capabilities and supported features
as exposed by the Power Management Controller.

Please refer to the below specification for more details on PMC features.
http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html

The current version of this driver exposes SLP_S0_RESIDENCY counter.
This counter can be used for detecting fragile SLP_S0 signal related
failures and take corrective actions when PCH SLP_S0 signal is not
asserted after kernel freeze as part of suspend to idle flow
(echo freeze > /sys/power/state).

Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it
detects favorable conditions to enter its low power mode. As a
pre-requisite the SoC should be in deepest possible Package C-State
and devices should be in low power mode. For example, on Skylake SoC
the deepest Package C-State is Package C10 or PC10. Suspend to idle
flow generally leads to PC10 state but PC10 state may not be sufficient
for realizing the platform wide power potential which SLP_S0 signal
assertion can provide.

SLP_S0 signal is often connected to the Embedded Controller (EC) and the
Power Management IC (PMIC) for other platform power management related
optimizations.

In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes
power gated + PLL Idle.

As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed
as an API and also debugfs features are added to indicate SLP_S0 signal
assertion residency in microseconds.

echo freeze > /sys/power/state

Linus Torvalds 1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,

Merge tag 'gpio-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for kernel cycle v4.7:

  Core infrastructural changes:

   - Support for natively single-ended GPIO driver stages.

     This means that if the hardware has registers to configure open
     drain or open source configuration, we use that rather than (as we
     did before) try to emulate it by switching the line to an input to
     get high impedance.

     This is also documented throughly in Documentation/gpio/driver.txt
     for those of you who did not understand one word of what I just
     wrote.

   - Start to do away with the unnecessarily complex and unitelligible
     ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
     evolutional artifact from the time when the GPIO subsystem was
     unmaintained.

     Archs can now just select GPIOLIB and be done with it, cleanups to
     arches will trickle in for the next kernel.  Some minor archs ACKed
     the changes immediately so these are included in this pull request.

   - Advancing the use of the data pointer inside the GPIO device for
     storing driver data by switching the PowerPC, Super-H Unicore and
     a few other subarches or subsystem drivers in ALSA SoC, Input,
     serial, SSB, staging etc to use it.

   - The initialization now reads the input/output state of the GPIO
     lines, so that each GPIO descriptor knows - if this callback is
     implemented - whether the line is input or output.  This also
     reflects nicely in userspace "lsgpio".

   - It is now possible to name GPIO producer names, line names, from
     the device tree.  (Platform data has been supported for a while).
     I bet we will get a similar mechanism for ACPI one of those days.
     This makes is possible to get sensible producer names for e.g.
     GPIO rails in "lsgpio" in userspace.

  New drivers:

   - New driver for the Loongson1.

   - The XLP driver now supports Broadcom Vulcan ARM64.

   - The IT87 driver now supports IT8620 and IT8628.

   - The PCA953X driver now supports Galileo Gen2.

   - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
     support the new single ended callback for open drain and in some
     cases open source.

   - Implement the .get_direction() callback for a few more drivers like
     PL061, Xgene.

   - Paul Gortmaker combed through the drivers and de-modularized those
     who are not really modules.

Azael Avalos a30b8f81d9 toshiba_acpi: Fix regression caused by hotkey enabling value
Commit 52cbae0127 ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.

This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.

Fixes bugs 113331 and 114941.

Michał Kępień 4f62568c1f fujitsu-laptop: Support radio LED
Lifebook E734/E744/E754 has a LED which the manual calls "radio
components indicator".  It should be lit when any radio transmitter is
enabled.  Its state can be read and set using ACPI (FUNC interface,
RFKILL method).

Since the Lifebook E734/E744/E754 only has a button (as compared to a
slider) for enabling/disabling radio transmitters, I believe the LED in
question is meant to indicate whether all radio transmitters are
currently on or off.  However, pressing the radio toggle button does not
automatically change the hardware state of the transmitters: it looks
like this machine relies on soft rfkill.

As for detecting whether the LED is present on a given machine, I had to
resort to educated guesswork.  I assumed this LED is present on all
devices which have a radio toggle button instead of a slider.  My
Lifebook E744 holds 0x01010001 in BTNI.  By comparing the bits and
buttons with those of a Lifebook E8420 (BTNI=0x000F0101, has a slider),
I put my money on bit 24 as the indicator of the radio toggle button
being present.  Furthermore, bit 24 is also clear on the S7020 which
does not have the toggle button or an RF LED.

Figuring out how the LED is controlled was more deterministic as all it
took was decompiling the DSDT and taking a look at method S000 (the
RFKILL method of the FUNC interface).

The LED control method implemented here is unsuitable for use with
"heavy" LED triggers, like phy0rx.  Once blinking frequency achieves a
certain level, the system hangs.

Maciej S. Szmigiero fffcad87d4 hp-wmi: Remove GPS rfkill support via pre-2009 interface
GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
and hp_wmi_get_hw_state() to query its current hard and soft block state,
respectively.

In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
in an int value returned by firmware to get current block state: 0x200 <<
(r * 8) which with r being 3 for GPS results in overflow and mask of zero.
The same goes for hp_wmi_get_hw_state().

This effectively means that GPS rfkill on this WMI interface is considered
always both hard and soft blocked.

Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
this block to hardware firmware at least on my old nc6400 gets confused and
sets both hard and soft blocks on WiFi and BT.

This happens for example on hp-wmi module load.

Since due to overflow described above it is dubious that this ever worked
correctly and HP laptops with modems having GPS support seem to all have
been released well past year 2009 let's just remove GPS rfkill support via
pre-2009 WMI interface.

Maciej S. Szmigiero c7805e5459 hp-wmi: fix unregister order in hp_wmi_rfkill_setup() once again
rfkill registration order in hp_wmi_rfkill_setup() is:
1) WiFi,
2) BT,
3) WWAN,
5) GPS.

Unregistration when cleaning up on error return should happen in reverse
order.

This means that: If BT rfkill fails to be allocated we possibly need to
first unregister WiFi rfkill before destroying it.

The same goes with (WWAN, BT) and (GPS, WWAN) pairs.

Also, if WWAN rfkill fails to register we need to (possibly) unregister BT
not the GPS one.  And if GPS rfkill fails to register we need to unregister
WWAN not the BT one.

We never need to unregister GPS rfkill here since if GPS rfkill
registration succeeds this function returns without error so no cleanup is
necessary.

Michał Kępień aaf3a5e775 dell-wmi: support Dell Inspiron M5110
Similarly to Dell Vostro V131, Dell Inspiron M5110 also requires an
SMBIOS request to be issued in order for WMI events to be generated and
does not raise an i8042 interrupt when the Dell Instant Launch hotkey is
pressed.  However, the event code for that hotkey on this machine is
0xe029, so add it to the legacy keymap.

Michał Kępień 13f5059ac5 dell-wmi: properly process Dell Instant Launch hotkey
On models on which an SMBIOS request needs to be issued in order for WMI
events to be generated, pressing the Dell Instant Launch hotkey does not
raise an i8042 interrupt - only a WMI event is generated (0xe025 on Dell
Vostro V131).  As that WMI event is the only way the kernel will be
notified about pressing the Dell Instant Launch hotkey on such machines,
the relevant keymap entry has to be changed to a KE_KEY one.  However,
the same WMI event should still be ignored on machines which do not
require an SMBIOS request for enabling WMI, so filter it conditionally
in dell_wmi_process_key().

Michał Kępień e09c4d5b15 dell-wmi: enable receiving WMI events on Dell Vostro V131
On some laptop models (e.g. Dell Vostro V131), WMI events are not
generated until a specific SMBIOS request is issued to register an event
listener [1].  As there seems to be no ACPI method or SMBIOS request to
determine without possible side effects whether a given machine needs to
issue this SMBIOS request in order to receive WMI events, DMI matching
is used to whitelist the models which need it.

Paul Gortmaker f52ab44fb7 platform/x86: Make intel_scu_ipc explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/platform/x86/Kconfig:config INTEL_SCU_IPC
drivers/platform/x86/Kconfig:   bool "Intel SCU IPC Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_pci_driver() uses the same init level priority as
builtin_pci_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We don't replace module.h with init.h since the file already has that.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Qipeng Zha 1f1ae997fd intel_pmc_ipc: Avoid pending IPC1 command during legacy suspend
During legacy suspend flow, IPC1 commands are being requested
from opregion driver. But the PMC_IPC1 command will timeout as example:

[  281.444600] ipc_debug##: ipc_send_command: cmd=0x201ff,
[  281.444648] wbuf[0]=0x4ea6
[  281.444668] wbuf[1]=0x0
[  281.444674] wbuf[2]=0x0
[  281.444676] wbuf[3]=0x0
[  284.446467] pmc-ipc-plat INT34D2:00: IPC timed out, TS=0x4, CMD=0x200ff

This is because before the opregion driver could send IPC1 commands,
the PMC_IPC irq is already suspended. Which makes the IPC command to
timeout.

Solution: register pmc_ipc irq as IRQF_NO_SUSPEND

Andy Lutomirski a464afb958 dell-wmi: Support new hotkeys on the XPS 13 9350 (Skylake)
The XPS 13 9350 sends WMI keypress events that aren't enumerated in
the DMI table.  Add a table listing them.  To avoid breaking things
that worked before, these un-enumerated hotkeys won't be used if the
DMI table maps them to something else.

FWIW, it appears that the DMI table may be a legacy thing and we
might want to rethink how we handle events in general.  As an
example, a whole lot of things map to KEY_PROG3 via the DMI table.

This doesn't send keypress events for any of the new events.  They
appear to all be handled by other means (keyboard illumination is
handled automatically and rfkill is handled by intel-hid).

Clean this up: replace the hardcoded header length with a sizeof and

change is that a 7-byte table (which is nonsensical) will now be
treated as absent instead of as valid but empty.

Lukas Wunner 2413306c25 apple-gmux: Add helper for presence detect
Centralize gmux' ACPI HID in a header file and add apple_gmux_present().
This can be used by other drivers to activate quirks specific to dual
GPU MacBook Pros & Mac Pros. The alternative would be to hardcode DMI
or PCI IDs and amend them whenever Apple introduces a new machine.

Lukas Wunner f798d96528 apple-gmux: Add switch_ddc support
Originally by Seth Forshee <seth.forshee@canonical.com>, 2012-10-04:
    The gmux allows muxing the DDC independently from the display, so
    support this functionality. This will allow reading the EDID for the
    inactive GPU, fixing issues with machines that either don't have a
    VBT or have invalid mode data in the VBT.

Modified by Lukas Wunner <lukas@wunner.de>, 2015-04 - 2015-12:
    Change semantics of ->switch_ddc handler callback to return previous
    DDC owner. Original version tried to determine previous DDC owner
    with find_active_client() in vga_switcheroo but this fails if the
    inactive client registers before the active client.

    v2.4: Retain semantics of ->switchto handler callback to switch all
          pins, including DDC (Daniel Vetter)

    v4:   Advertise ->switch_ddc handler callback only on the pre-retina
          Macbook Pro. The retina uses eDP instead of LVDS and gmux no
          longer does the muxing itself but merely controls an external
          mux. That mux is incapable of switching the AUX channel
          separately from the main link. It's an NXP CBTL06142
          (alternate parts: TI HD3SS212, Pericom PI3VDP12412,
          see datasheets below).

    v5:   Rebase on "apple-gmux: Track switch state".
          Rebase on "vga_switcheroo: Add handler flags infrastructure".
          Rebase on 5d170139eb ("Constify vga_switcheroo_handler"),
          requires 2 structs, 1x with ->switchto for pre-retinas,
          1x without for retinas).
          Add error message if handler registration with vga_switcheroo
          fails.

Lukas Wunner 3e46304e74 apple-gmux: Track switch state
gmux has 3 switch registers:

* GMUX_PORT_SWITCH_DISPLAY switches the panel
* GMUX_PORT_SWITCH_DDC switches the panel's DDC lines
  (only on pre-retinas; on retinas this is a no-op)
* GMUX_PORT_SWITCH_EXTERNAL switches the external DP port(s)
  (only on models without Thunderbolt, i.e. introduced before 2011;
  those with Thunderbolt switch only HPD/AUX, not the main link)

Currently we switch all 3 registers in unison.

gmux does not preserve the switch state during suspend, so we currently
read GMUX_PORT_SWITCH_DISPLAY before suspend and restore all 3 registers
to this value on resume.

With the upcoming ->switch_ddc callback, GMUX_PORT_SWITCH_DDC may
temporarily contain a different value than the other 2 registers.
If we happen to suspend at this moment, we'll write an incorrect
value to GMUX_PORT_SWITCH_DDC on resume.

Also, on models with Thunderbolt the integrated GPU is unable to drive
the external DP port(s), so we want to keep GMUX_PORT_SWITCH_EXTERNAL
permanently switched to the discrete GPU on those machines.

Consequently we can no longer assume that GMUX_PORT_SWITCH_DISPLAY
represents the correct value for all 3 registers on suspend.

Track the state of all 3 registers: Add gmux_read_switch_state() and
gmux_write_switch_state(). Instead of reading the switch state on
every suspend, read it once on driver initialization so that we know
the current switch state all the time. (This allows us to use some
optimizations and shortcuts, e.g. we can skip switching DDC if we
know that it's already switched to the requested GPU.) Change the
->switchto callback to use gmux_write_switch_state().

Lukas Wunner 156d7d4120 vga_switcheroo: Add handler flags infrastructure
Allow handlers to declare their capabilities and allow clients to
obtain that information. So far we have these use cases:

* If the handler is able to switch DDC separately, clients need to
  probe EDID with drm_get_edid_switcheroo(). We should allow them
  to detect a capable handler to ensure this function only gets
  called when needed.

* Likewise if the handler is unable to switch AUX separately, the active
  client needs to communicate link training parameters to the inactive
  client, which may then skip the AUX handshake and set up its output
  with these pre-calibrated values (DisplayPort specification v1.1a,
  section 2.5.3.3). Clients need a way to recognize such a situation.

The flags for the radeon_atpx_handler and amdgpu_atpx_handler are
initially set to 0, this can later on be amended with
  handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC;
when a ->switch_ddc callback is added.

 "This includes fixes on top of the previous batch of PM+ACPI updates
  and some new material as well.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over
  system suspend/resume cycles if they have been runtime-suspended
  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

Pali Rohár 481fe5be82 dell-wmi: Process only one event on devices with interface version 0
BIOS/ACPI on devices with WMI interface version 0 does not clear buffer
before filling it. So next time when BIOS/ACPI send WMI event which is
smaller as previous then it contains garbage in buffer from previous event.

BIOS/ACPI on devices with WMI interface version 1 clears buffer and
sometimes send more events in buffer at one call.

Since commit 83fc44c32a ("dell-wmi: Update code for processing WMI
events") dell-wmi process all events in buffer (and not just first).

To prevent reading garbage from the buffer we process only the first
event on devices with WMI interface version 0.

João Paulo Rechi Vita f6a6bbae04 platform/x86: Add Asus Wireless Radio Control driver
Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):

Azael Avalos 65e3cf9c0f toshiba_acpi: Fix keyboard backlight sysfs entries not being updated
Certain Toshiba models with the second generation keyboard backlight
(type 2) do not generate the keyboard backlight changed event (0x92),
and thus, the sysfs entries are never being updated.

This patch adds a workquee and a global boolean variable to address
the issue.

For those models that do generate the event, the sysfs entries are
being updated via the *notify function and the boolean is set to
true to avoid a second call to update the entries.

For those models that do not generate the event, the workquee is
used to update the sysfs entries and also to emulate the event via
netlink, to make userspace aware of such change.

Linus Torvalds 58cf279aca GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes:
 
 - In struct gpio_chip, rename the .dev node to .parent to better reflect
   the fact that this is not the GPIO struct device abstraction. We will
   add that soon so this would be totallt confusing.
 
 - It was noted that the driver .get_value() callbacks was
   sometimes reporting negative -ERR values to the gpiolib core, expecting
   them to be propagated to consumer gpiod_get_value() and gpio_get_value()
   calls. This was not happening, so as there was a mess of drivers
   returning negative errors and some returning "anything else than zero"
   to indicate that a line was active. As some would have bit 31 set to
   indicate "line active" it clashed with negative error codes. This is
   fixed by the largeish series clamping values in all drivers with
   !!value to [0,1] and then augmenting the code to propagate error codes
   to consumers. (Includes some ACKed patches in other subsystems.)
 
 - Add a void *data pointer to struct gpio_chip. The container_of() design
   pattern is indeed very nice, but we want to reform the struct gpio_chip
   to be a non-volative, stateless business, and keep states internal to
   the gpiolib to be able to hold on to the state when adding a proper
   userspace ABI (character device) further down the road. To achieve this,
   drivers need a handle at the internal state that is not dependent on
   their struct gpio_chip() so we add gpiochip_add_data() and
   gpiochip_get_data() following the pattern of many other subsystems.
   All the "use gpiochip data pointer" patches transforms drivers to this
   scheme.
 
 - The Generic GPIO chip header has been merged into the general
   <linux/gpio/driver.h> header, and the custom header for that removed.
   Instead of having a separate mm_gpio_chip struct for these generic
   drivers, merge that into struct gpio_chip, simplifying the code and
   removing the need for separate and confusing includes.
 
 Misc improvements:
 
 - Stabilize the way GPIOs are looked up from the ACPI legacy
   specification.
 
 - Incremental driver features for PXA, PCA953X, Lantiq (patches from the
   OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
 
 New drivers:
 
 - Add a GPIO chip to the ALSA SoC AC97 driver.
 
 - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
   the branch is merged here too to account for infrastructural changes).
 
 - The sx150x driver now supports the sx1502.

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "Here is the bulk of GPIO changes for v4.5.

  Notably there are big refactorings mostly by myself, aimed at getting
  the gpio_chip into a shape that makes me believe I can proceed to
  preserve state for a proper userspace ABI (character device) that has
  already been proposed once, but resulted in the feedback that I need
  to go back and restructure stuff.  So I've been restructuring stuff.
  On the way I ran into brokenness (return code from the get_value()
  callback) and had to fix it.  Also, refactored generic GPIO to be
  simpler.

  Some of that is still waiting to trickle down from the subsystems all
  over the kernel that provide random gpio_chips, I've touched every
  single GPIO driver in the kernel now, oh man I didn't know I was
  responsible for so much...

  Apart from that we're churning along as usual.

  I took some effort to test and retest so it should merge nicely and we
  shook out a couple of bugs in -next.

  Infrastructural changes:

   - In struct gpio_chip, rename the .dev node to .parent to better
     reflect the fact that this is not the GPIO struct device
     abstraction.  We will add that soon so this would be totallt
     confusing.

   - It was noted that the driver .get_value() callbacks was sometimes
     reporting negative -ERR values to the gpiolib core, expecting them
     to be propagated to consumer gpiod_get_value() and gpio_get_value()
     calls.  This was not happening, so as there was a mess of drivers
     returning negative errors and some returning "anything else than
     zero" to indicate that a line was active.  As some would have bit
     31 set to indicate "line active" it clashed with negative error
     codes.  This is fixed by the largeish series clamping values in all
     drivers with !!value to [0,1] and then augmenting the code to
     propagate error codes to consumers.  (Includes some ACKed patches
     in other subsystems.)

   - Add a void *data pointer to struct gpio_chip.  The container_of()
     design pattern is indeed very nice, but we want to reform the
     struct gpio_chip to be a non-volative, stateless business, and keep
     states internal to the gpiolib to be able to hold on to the state
     when adding a proper userspace ABI (character device) further down
     the road.  To achieve this, drivers need a handle at the internal
     state that is not dependent on their struct gpio_chip() so we add
     gpiochip_add_data() and gpiochip_get_data() following the pattern
     of many other subsystems.  All the "use gpiochip data pointer"
     patches transforms drivers to this scheme.

   - The Generic GPIO chip header has been merged into the general
     <linux/gpio/driver.h> header, and the custom header for that
     removed.  Instead of having a separate mm_gpio_chip struct for
     these generic drivers, merge that into struct gpio_chip,
     simplifying the code and removing the need for separate and
     confusing includes.

  Misc improvements:

   - Stabilize the way GPIOs are looked up from the ACPI legacy
     specification.

   - Incremental driver features for PXA, PCA953X, Lantiq (patches from
     the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48

  New drivers:

   - Add a GPIO chip to the ALSA SoC AC97 driver.

   - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
     but the branch is merged here too to account for infrastructural
     changes).

   - The sx150x driver now supports the sx1502"

Hans de Goede 95565f8841 ACPI / video: Revert "thinkpad_acpi: Use acpi_video_handles_brightness_key_presses()"
acpi_video_handles_brightness_key_presses()'s may return false if the i915
driver is not loaded yet when thinkpad_acpi loads, and then return true
after the i915 driver has loaded. This means that thinkpad_acpi cannot
use it as is since thinkpad_acpi caches the return value.

Lukas Wunner 3d7b75fdae apple-gmux: Add initial documentation
Document what I've learned so far about the gmux so that we can
collaboratively reverse-engineer its remaining unknown bits
without everyone having to start from scratch.

The DOC sections are bound together in the gpu.tmpl DocBook
under a new vga_switcheroo "Handlers" chapter. Eventually
this should be amended with documentation about the four other
handlers that exist so far (nouveau v1 DSM, nouveau Optimus DSM,
radeon ATPX, amdgpu ATPX).

Requires kernel-doc with asciidoc support.

The EFI variable was reverse-engineered by Bruno Bierbaumer
<bruno@bierbaumer.net> and Andreas Heider <andreas@meetr.de>.

Some of the remaining open questions:

* How are vblank intervals synchronized on retinas to achieve seamless
  switching? Is the DP mux capable of this? It's not mentioned in the
  data sheets. Or is it done at the OS level, i.e. do we have to
  synchronize vblank intervals between DRM drivers? There's a signal
  coming from the panel connector and going into gmux, could this be
  the vblank signal as received by the panel to properly time the
  switch?

* On retinas there's an I2C bus between gmux and the connector of the
  right I/O board, apparently leading to the Parade PS8401A HDMI
  repeater. What is this for, is it controlled via gmux registers?
  Data sheet:
  http://www.paradetech.com/products/jitter-cleaning-repeaters/ps8401/

* On retinas there's an I2C bus between gmux and the LED driver.
  Pre-retinas connected the LED driver to SMBUS. Are there additional
  gmux registers on retinas to control it?

* The MacPro6,1 2013 also has a gmux, the same Renesas R4F2113 as the
  retina MacBook Pro. The Mac Pro doesn't have a built-in display,
  so what is its purpose? Power control of the dual FirePro GPUs?
  Switching of the external DP/Thunderbolt ports? The iFixit teardown
  clearly shows one TI HD3SS212 DisplayPort mux on the logic board next
  to one of the three Thunderbolt controllers. However six muxes would
  be necessary to switch all six ports between GPUs. The mux is probably
  necessary for one of the display configurations allowed by Apple,
  but which one?
  https://www.ifixit.com/Teardown/Mac+Pro+Late+2013+Teardown/20778
  https://d3nevzfk7ii3be.cloudfront.net/igi/fELBTnt31QhnDsqq.huge
  https://support.apple.com/en-us/HT202801

* Registers we haven't decoded yet:
  0x700 32 Bit configmap?
  0x708 32 Bit power sequence?
  0x712  8 Bit status of clock from panel on retinas?
  0x713  8 Bit dito?
  0x724 16 Bit backlight, raw value?
  0x760 32 Bit backlight
  0x764 32 Bit backlight
  0x768  8 Bit backlight
  0x76a 16 Bit backlight
  0x76c 16 Bit backlight
  0x76e 16 Bit backlight
  0x77f        edp/dp/hdmi probe? retina only.

* Addition by Bruno Prémont <bonbons@linux-vserver.org>:
  "Missing is also precise knowledge as to what the gmux depends on.
  From behavioral reports, it is somehow sensitive to VGA IO/MEM
  routing (it apparently needs the routing to go to integrated GPU,
  not discrete GPU).
  When the routing is inappropriate backlight control IO just reads back
  as 0xFF (and eventually gmux IO in general does so)."

Linus Walleij 58383c7842 gpio: change member .dev to .parent
The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.

This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:

@@
struct gpio_chip *var;
@@
-var->dev
+var->parent

and:

@@
struct gpio_chip var;
@@
-var.dev
+var.parent

and:

@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent

Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.

This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.

Dan Carpenter b829834016 asus-wmi: fix error handling in store_sys_wmi()
The asus_wmi_get_devstate_simple() returns 0-1 on success.  In theory
according to static checkers, it can return either -EIO or -ENODEV on
failure.  Currently the error handling code only handles -ENODEV and
-EIO is treated as success.  Let's make it handle the -EIO error as
well.

It's possible that it can't actually return -EIO and this patch is not
needed but in that case this patch is harmless and silences a static
checker warning so it's still worth it.

Hans de Goede f71c882dd4 ideapad-laptop: Add Lenovo Yoga 900 to no_hw_rfkill dmi list
Like some of the other Yoga models the Lenovo Yoga 900 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 900 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

Arnd Bergmann c789fffc56 ideapad-laptop: include Yoga 3 1170 in add rfkill whitelist
This changes the entry to the whitelist of machines that do not have
a physical rfkill switch. Unfortunately, the Yoga 3 generation seems
to use upper-case letters for the YOGA 3 Pro-1370, while it uses normal
capitalization for its Yoga 3 1170 and 1470 siblings.

In order to catch all variants of the Yoga 3, I'm changing both
the entry for the 1470 (using "Yoga" as the name) and the entry for
the Pro 1370 (using all-caps "YOGA") to not match the exact model number
but only the generation. This way, the 1170 and 1470 models share one
entry, but if the firmware changes from one format to the other, it will
still work.

The second entry for Yoga 2 Pro that was recently added for some
reason ended up not being added in alphanumeric order, and I'm
moving the Yoga 3 1470 entry down while making the change, so they
are sorted more logically.

Arnd Bergmann 74caab996c ideapad-laptop: add support for Yoga 3 ESC key
The ideapad-laptop handles most special keys on various Lenovo Laptops
including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have
one important exception, which is the Fn-ESC combination.

On other Lenovo Laptops, this is FnLock, which switches the function keys
between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1,
F2, F3, ...) behavior. On the new machines, FnLock is only available
through BIOS setup (possibly through a yet-to-be-implemented feature
in this driver) but not through Fn-ESC, but instead the ESC key itself
switched between ESC and a "Paper Display" app for Windows.

Unfortunately, that means that you can never have both ESC *and* the
function keys working at the same time without needing to press Fn on
one of them.
As pointed out in the official Lenovo Forum by dozens of users, this
makes the machine rather useless for any serious work [1].

I have now studied the ACPI DSDT one more time and found the event
that is generated for the ESC key. Unlike all other key events on this
machine, it is actually a WMI, while the other ones are read from the
embedded controller.

I am now installing a WMI notifier that uses the event number from the
WMI subsystem as the scancode. The only event number generated here is
'128', and that fits in nicely with the two existing ranges of scancodes
used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for
the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS.

The only sane way to handle this button (in absence of the Windows Paper
Display driver) seems to be to have it emit KEY_ESC, so that is what
I use as the default. Should any user ever want to overwrite the default,
they can install their own keymap.

To ensure that we can still build the driver without adding a CONFIG_WMI
dependency, all new code is enclosed in #ifdef.

Lee, Chun-Yi c460228086 acer-wmi: remove threeg and interface sysfs interfaces
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and
provides the threeg rfkill interface. So the sysfs interface of 3G is
no longer necessary now.

The 7b8aca65 patch added kernel information log to remind to user space
for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch
updated the interface removing time to 2014.

I think the 3 years lead time is enough for user space application to use
rfkill instead of sysfs interface to control 3G device.

This patch removes code about threeg sysfs interface. And it also removes the
unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi
driver on the machine. The information is already exposed by the acer-wmi
initial log.

Azael Avalos 14991fc7df platform/x86: Toshiba WMI Hotkey Driver
Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5a ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the proper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

Roald Frederickx d9a427ec81 compal-laptop: Add charge control limit
Add charge control limit to the power supply subsystem of the Compal
platform driver.

This apparently was present in the original driver by Cezary Jackiewicz
at http://eko.one.pl/index.php?page=compal-laptop but it seems to have been
overlooked.

The Kconfig description is updated to reflect this addition. It now also
mentions the hwmon interface that was already present.

Azael Avalos 10e6aaabc3 toshiba_acpi: Remove unneeded u32 variables from *setup_keyboard
The function toshiba_acpi_setup_keyboard currently has two u32 variables
used to store the Hotkey Event Type and the result of the HCI_SYSTEM_EVENT
query.

This patch removes those two variables, as we already have a global
variable named "hotkey_event_type" and the result of the HCI_SYSTEM_EVENT
query can be checked directly from the function.

Azael Avalos 52cbae0127 toshiba_acpi: Change default Hotkey enabling value
The driver currently uses the hotkey enabling value of 0x09 to enable
hotkey events, but windows uses a different value (0x01).

All Toshiba laptops accept the following "hotkey" parameters:
0x01 - Enable hotkey and system events.
0x03 - Enable system events only.
0x09 - Enable hotkey events only.
0x0b - Disable (hotkey and system) events.

This patch changes the default hotkey enabling value from 0x09 to 0x01,
enabling both the hotkey and system events.

Kyle Evans 8a1513b493 hp-wmi: limit hotkey enable
Do not write initialize magic on systems that do not have
feature query 0xb. Fixes Bug #82451.

Redefine FEATURE_QUERY to align with 0xb and FEATURE2 with 0xd
for code clearity.

Add a new test function, hp_wmi_bios_2008_later() & simplify
hp_wmi_bios_2009_later(), which fixes a bug in cases where
an improper value is returned. Probably also fixes Bug #69131.

Azael Avalos 53147b6cab toshiba_acpi: Fix hotkeys registration on some toshiba models
Commit a2b3471b5b ("toshiba_acpi: Use the Hotkey Event Type function
for keymap choosing") changed the *setup_keyboard function to query for
the Hotkey Event Type to help choose the correct keymap, but turns out
that here are certain Toshiba models out there not implementing this
feature, and thus, failing to continue the input device registration and
leaving such laptops without hotkey support.

This patch changes such check, and instead of returning an error if
the Hotkey Event Type is not present, we simply inform userspace about it,
changing the message printed from err to notice, making the function
responsible for registering the input device to continue.

This issue was found on a Toshiba Portege Z30-B, but there might be
some other models out there affected by this regression as well.

Rasmus Villemoes 85b4e4eb2f wmi: Remove private %pUL implementation
The work performed by wmi_gtoa is equivalent to simply sprintf(out,
"%pUL", in), so one could replace its body by this. However, most
users feed the result directly as a %s argument to some other function
which also understands the %p extensions (they all ultimately use
vsnprintf), so we can eliminate some stack buffers and quite a bit of
code by just using %pUL directly.

In wmi_dev_uevent I'm not sure whether there's room for a
nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
equivalent sprintf call.
