This splits up the dell-smbios driver into two drivers:
* dell-smbios
* dell-smbios-smm
dell-smbios can operate with multiple different dispatcher drivers to
perform SMBIOS operations.
Also modify the interface that dell-laptop and dell-wmi use align to this
model more closely. Rather than a single global buffer being allocated
for all drivers, each driver will allocate and be responsible for it's own
buffer. The pointer will be passed to the calling function and each
dispatcher driver will then internally copy it to the proper location to
perform it's call.
Add defines for calls used by these methods in the dell-smbios.h header
for tracking purposes.

All communication on individual GUIDs should occur in separate drivers.
Allowing a driver to communicate with the bus to another GUID is just
a hack that discourages drivers to adopt the bus model.
The information found from the WMI descriptor driver is now exported
for use by other drivers.

The fusb302 driver as merged in staging uses "typec_fusb302" as i2c-id
rather then just "fusb302" and needs us to set a number of device-
properties, adjust the intel_cht_int33fe driver accordingly.
One of the properties set is max-snk-mv which makes the fusb302 driver
negotiate up to 12V charging voltage, which is a bad idea on boards
which are not setup to handle this, so this commit also adds 2 extra
sanity checks to make sure that the expected Whiskey Cove PMIC +
TI bq24292i charger combo, which can handle 12V, is present.

Current implementations of Intel Thunderbolt controllers will go
into a low power mode when not in use.
Many machines containing these controllers also have a GPIO wired up
that can force the controller awake. This is offered via a ACPI-WMI
interface intended to be manipulated by a userspace utility.
This mechanism is provided by Intel to OEMs to include in BIOS.
It uses an industry wide GUID that is populated in a separate _WDG
entry with no binary MOF.
This interface allows software such as fwupd to wake up thunderbolt
controllers to query the firmware version or flash new firmware.

Using a dedicated Kconfig option for enabling debugging means the user
may be forced to recompile their kernel in order to gather debugging
information, which is inconvenient. Replace custom debugging
infrastructure with standard logging functions, taking advantage of
dynamic debug. Replace a pr_info() call inside an ACPI callback with an
acpi_handle_info() call.
The following mapping was used:
- FUJLAPTOP_DBG_ERROR -> acpi_handle_err()
- FUJLAPTOP_DBG_WARN -> acpi_handle_info() / dev_info()
- FUJLAPTOP_DBG_INFO -> acpi_handle_debug()
- FUJLAPTOP_DBG_TRACE -> acpi_handle_debug() / dev_dbg()
This means that some events which used to only be logged when the user
explicitly requested it will now be logged by default:
- ACPI method evaluation errors,
- unknown ACPI notification codes,
- unknown hotkey scancodes.
The first type of events should happen rarely, if ever at all. The rest
is interesting from driver development perspective as their presence in
the logs will mean the driver is unaware of certain events, handling of
which should be implemented.

Some peripherals on Bay Trail and Cherry Trail platforms signal a
Power Management Event (PME) to the Power Management Controller (PMC)
to wakeup the system. When this happens software needs to explicitly
clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
IRQ storm on IRQ 9.
This is modelled in ACPI through the INT0002 ACPI device, which is
called a "Virtual GPIO controller" in ACPI because it defines the
event handler to call when the PME triggers through _AEI and _L02
methods as would be done for a real GPIO interrupt in ACPI.
This commit adds a driver which registers the Virtual GPIOs expected
by the DSDT on these devices, letting gpiolib-acpi claim the
virtual GPIO and install a GPIO-interrupt handler which call the _L02
handler as it would for a real GPIO controller.

Many laptops (and maybe servers?) have embedded WMI Binary MOF metadata.
We do not yet have open-source tools for processing the data, although
one is in the works thanks to Pali:
https://github.com/pali/bmfdec
There is currently no interface to get the data in the first place. By
exposing it, we facilitate the development of new tools.
This is based on the original work of Andy Lutomirski <luto@kernel.org>,
but contains several modifications in response to various reviews.

PEAQ is a new European OEM, I've bought one of their 2-in-1 x86 devices,
which is actually quite a nice device. Under Windows it has Dolby
software for "better" sound and you can select different equalizer
presets using a special button.
This WMI interface for this button is not really nice, as it does not do
notifies (it really does not I triple checked), but since I had already
figured out the entire WMI interface for this I decided to go the full
mile anyway and implement a WMI based input driver for this using
input_polldev since, well, we need to poll.
This commit adds support for this button making it report KEY_SOUND
input events. KEY_SOUND is already used in various places to switch
sound into theatre mode and things like that so it seems appropriate
here.

Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.
Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.
Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.
(*) It looks like the configuration was never tested with
INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

The dell-led driver handles a specific WMI GUID present on some Dell
laptops and as such it belongs in the x86 platform driver subsystem.
Source code is moved along with the relevant Kconfig and Makefile
entries, with some minor modifications:
- Kconfig option is renamed from CONFIG_LEDS_DELL_NETBOOKS to
CONFIG_DELL_WMI_LED,
- the X86 Kconfig dependency is removed as the whole
drivers/platform/x86 menu depends on it, so there is no need to
duplicate it,
- the name of the module's source file is removed from the header
comment to avoid the need to update it in the future.

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

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
automatically whenever a driver which needs it is selected.
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
needed (n is the default default.)

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".

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"

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.

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.

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.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a

is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):
