Guenter Roeck 0ff44b0fd3 Input: maplecontrol - drop unnecessary call to input_set_drvdata
Since there is no call to dev_get_drvdata() or input_get_drvdata(),
the call to input_set_drvdata() is unnecessary and can be dropped.

This can happen in cases like bug #102951[1], so add a proper debug msg
as done in wait_read. Also, change wait_read debug message to differ from

David Lechner 9e54924432 Input: pwm-beeper - add optional amplifier regulator
This adds an optional regulator to the pwm-beeper device. This regulator
acts as an amplifier. The amplifier is only enabled while beeping in order
to reduce power consumption.

Tested on LEGO MINDSTORMS EV3, which has a speaker connected to PWM through
an amplifier.

Dmitry Torokhov e9728f0dd7 Input: pwm-beeper - fix race when suspending
Usually userspace sends SND_BELL and SND_TONE events, and by the time
pwm_beeper_suspend() runs userpsace is already frozen, but theoretically
in-kernel users may send these events too, and that may cause
pwm_beeper_event() scheduling another work after we canceled it.

Let's introduce a "suspended" flag and check it in pwm_beeper_event() to
avoid this race.

The soc_button_array driver was initializing (kzalloc) the
debounce_interval value to 0, leading to no debouncing at all,
while the buttons are simple mechanical switches.

This commit sets debounce_interval to 50ms to avoid spurious button
press reports both on press and release of the button. Note 50ms may
seem like a lot but soc_button_array is typically used with cheap
tablets, with not so great buttons. I tried 10ms on my tablet and it
is not enough, where as 50ms works well.

Aniroop Mathur 0eeecf6039 Input: edt_ft5x06 - change msleep to usleep_range for small msecs
msleep(1~20) may not do what the caller intends, and will often sleep
longer (~20 ms actual sleep for any value given in the 1~20ms range).  This
is not the desired behaviour for many cases like device resume time, device
suspend time, device enable time, retry logic, etc.  Thus, change msleep to
usleep_range for precise wakeups.

Cameron Gutman c01b5e7464 Input: xpad - don't depend on endpoint order
The order of endpoints is well defined on official Xbox pads, but
we have found at least one 3rd-party pad that doesn't follow the
standard ("Titanfall 2 Xbox One controller" 0e6f:0165).

Fortunately, we get lucky with this specific pad because it uses
endpoint addresses that differ only by direction. We know that
there are other pads out where this is not true, so let's go
ahead and fix this.

Dmitry Torokhov d79e141c1c Input: i8042 - Trust firmware a bit more when probing on X86
The error message "Can't read CTR while initializing i8042" appears on
Cherry Trail-based devices at each boot time:

  i8042: PNP: No PS/2 controller found. Probing ports directly.
  i8042: Can't read CTR while initializing i8042
  i8042: probe of i8042 failed with error -5

This happens because we historically do not trust firmware on X86 and,
while noting that PNP does not show keyboard or mouse devices, we still
charge ahead and try to probe the controller. Let's relax this a bit and if
results of PNP probe agree with the results of platform
initialization/quirks conclude that there is, in fact, no i8042.

While at it, let's avoid using x86_platform.i8042_detect() and instead
abort execution early if platform indicates that it can not possibly have
i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

Dmitry Torokhov 1a9027770f Input: i8042 - force synchronous probing of PNP drivers
We rely on the result of scanning PNP bus for keyboard and mouse devices to
decide whether we should continue initialization of i8042 driver or not, so
the probes can not be asynchronous.

Also, it is not a good idea to unbind either of the PNP devices while i8042
is running, so let's disable bind/unbind for the PNP drivers through sysfs
and rely on i8042 cleaning after itself properly. User can still unbind and
rebind entire i8042 and that will take care of PNP drivers as well.

msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, retry logic, etc.
Thus, change msleep to usleep_range for precise wakeups.

Linus Torvalds ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

 - Replace all kthread usages with simple works

Vladimir Zapolskiy 951a086437 Input: lpc32xx-keys - fix invalid error handling of a requested irq
Semantics of NR_IRQS is different on machines with SPARSE_IRQ option
disabled or enabled, in the latter case IRQs are allocated starting
at least from the value specified by NR_IRQS and going upwards, so
the check of (irq >= NR_IRQ) to decide about an error code returned by
platform_get_irq() is completely invalid, don't attempt to overrule
irq subsystem in the driver.

The change fixes lpc32xx_keys driver initialization on boot:

  lpc32xx_keys 40050000.key: failed to get platform irq
  lpc32xx_keys: probe of 40050000.key failed with error -22

First check if there are data available passed by the transport device.
If data available use these data. If there are no data available
try to read the rmi block if dsata are passed this way.

This is the way the other rmi function handlers will do this.

This patch is needed on HID devices because the firmware reads F03 data
registers and adds them to the HID attention report. Reading those
registers from the driver after the firmware read them will result in
invalid data.

The code uses of_property_read_u32 and expects positive values.  However,
the values are stored in signed int variables.  Additionally, the registers
values are also stored in signed variables without a good reason
(readl/writel expect u32).

The only time this caused a real bug was in the new average-samples
property, in which the property is numerically compared and implicitly
expected to be positive.

I believe it's better to change all the properties and registers to u32,
for consistency and warnings reduction.

Cameron Gutman ae3b4469db Input: xpad - fix Xbox One rumble stopping after 2.5 secs
Unlike previous Xbox pads, the Xbox One pad doesn't have "sticky" rumble
packets. The duration is encoded into the command and expiration is handled
by the pad firmware.

ff-memless needs pseudo-sticky behavior for rumble effects to behave
properly for long duration effects. We already specify the maximum rumble
on duration in the command packets, but it's still only good for about 2.5
seconds of rumble. This is easily reproducible running fftest's sine
vibration test.

It turns out there's a repeat count encoded in the rumble command. We can
abuse that to get the pseudo-sticky behavior needed for rumble to behave as
expected for effects with long duration.

By my math, this change should allow a single ff_effect to rumble for 10
minutes straight, which should be more than enough for most needs.

Dmitry Torokhov e9fb7cc638 Input: psmouse - disable automatic probing of BYD touchpads
BYD automatic protocol detection is extremely unreliable and is often
triggers false positives on regular mice, Sentelic touchpads, and other
devices. BYD has several documents that have recommended detection
sequence, but they conflict with each other and, as far as I can see, still
would not produce unique enough output to reliably differentiate BYD from
other PS/2 devices.

OEMs sourcing BYD devices also do not do us any favors by not supplying any
reasonable DMI data and instead leaving turds like "To Be Filled By O.E.M."
in place of vendor data, or "System Serial Number" as serial number.

On top of that BYD is not truly modern multitouch controller, but rather a
single-touch transitional device that only reports absolute coordinates at
the beginning of finger contact and then reverts to reporting
displacements, and thus not very precise; the only benefit from using BYD
mode vs the legacy PS/2 mode is possibility of edge scrolling.

Given the above, and the fact that BYD devices are somewhat uncommon, let's
disable automatic detection of BYD devices. Users who know they have BYD
trackpads or want to experiment can attempt to activate BYD protocol via
sysfs:

commit ef3714fdbc ("Input: bma150 - extend chip detection for bma180"),
adds bma180 chip-ids to the input bma150 driver, assuming that they are
100% compatible, but the bma180 is not compatible with the bma150 at all,
it has 14 bits resolution instead of 10, and it has quite different
control registers too.

Treating the bma180 as a bma150 wrt its data registers will just result
in throwing away the lowest 4 bits, which is not too bad. But the ctrl
registers are a different story. Things happen to just work but supporting
that certainly does not make treating the bma180 the same as the bma150
right.

Since some setups depend on the evdev interface the bma150 driver offers
on top of the bma180, we cannot simply remove the bma180 ids.

So this commit only removes the bma180 id when the bma180 iio driver,
which does treat the bma180 properly, is enabled.

Andrew Duggan 2775e52324 Input: synaptics-rmi4 - add parameters for dribble packets and palm detect gesture
The rmi_f11 driver currently disables dribble packets and the palm detect
gesture for all devices. This patch creates a parameter in the 2d sensor
platform data for controlling this functionality on a per device basis.

For more information on dribble packets:

Marcos Paulo de Souza 930e19248e Input: i8042 - skip selftest on ASUS laptops
On suspend/resume cycle, selftest is executed to reset i8042 controller.
But when this is done in Asus devices, subsequent calls to detect/init
functions to elantech driver fails. Skipping selftest fixes this problem.

An easier step to reproduce this problem is adding i8042.reset=1 as a
kernel parameter. On Asus laptops, it'll make the system to start with the
touchpad already stuck, since psmouse_probe forcibly calls the selftest
function.

This patch was inspired by John Hiesey's change[1], but, since this problem
affects a lot of models of Asus, let's avoid running selftests on them.

All models affected by this problem:
A455LD
K401LB
K501LB
K501LX
R409L
V502LX
X302LA
X450LCP

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with

as the mouse pointer won't move.

This patch makes the driver aware of both the crc_enabled=1 requirement and
the middle button, making the touchpad fully functional out-of-the-box.

Checking for error not null means the function always fails if the device
answers properly.

So given that we read 3 bytes and access those, better check that we
actually read those 3 bytes.

Arnd Bergmann 979987ded3 Input: ektf2127 - mark PM functions as __maybe_unused
The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro
to conditionally refer to the resume/suspend functions, which
causes a warning when CONFIG_PM_SLEEP is disabled:

drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function]
drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function]

We could either put these functions inside of an #ifdef or
add __maybe_unused annotations. This uses the second approach,
which is generally more foolproof.

Ville Ranki 9fb6de1b0b Input: joydev - recognize devices with Z axis as joysticks
Current implementation of joydev's input_device_id table recognizes only
devices with ABS_X, ABS_WHEEL or ABS_THROTTLE axes as joysticks.

There are joystick devices that do not have those axes, for example TRC
Rudder device. The device in question has ABS_Z, ABS_RX and ABS_RY axes
causing it not being detected as joystick.

This patch adds ABS_Z to the input_device_id list allowing devices with
ABS_Z axis to be detected correctly.

Hans Verkuil 51db013767 Input: serio - add hangup support
The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0
device.  It requires that you run inputattach in order to communicate with
it via serio.

This all works well, but it would be nice to have a udev rule to
automatically start inputattach. That too works OK, but the problem comes
when the USB device is unplugged: the tty hangup is never handled by the
serio framework so the inputattach utility never exits and you have to kill
it manually.

By adding this hangup callback the inputattach utility now properly exits
as soon as the USB device is unplugged.

The udev rule I used on my Debian sid system is:

SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service"

And /etc/systemd/system/pulse8-cec-inputattach@.service is as follows:

===============================================================
[Unit]
Description=inputattach for pulse8-cec device on %I

[Service]
Type=simple
ExecStart=/usr/local/bin/inputattach --pulse8-cec /dev/%I

Hans de Goede 43ba588346 Input: silead_gsl1680 - document firmware-name, fix implementation
The driver has supported touchscreen-fw-name to specify the firmware to
load since it has been merged, but this was omitted from the dt-binding
documentation.

During review of adding touchscreen-fw-name to the binding documentation
it was brought up that there is a standard property name called
"firmware-name" for this, which should be used.

Since there are no users of touchscreen-fw-name yet, this commit
adds documentation of "firmware-name" to the dt-binding documentation
and switches the driver over to use this.

This commit also makes the driver add a "silead/" prefix to the
firmware name from dt before calling request_firmware. That the
firmware files are stored under /lib/firmware/silead under Linux
is an implementation detail and does not belong in devicetree.

Add a driver to read group of GPIO lines and provide its status as a
numerical value as input event to the system. This will help in
interfacing devices, that can be connected over GPIOs, that provide
input to the system by driving GPIO lines connected to them like a
rotary dial or a switch.

For example, a rotary switch can be connected to four GPIO lines. The
status of the GPIO lines reflect the actual position of the rotary
switch dial. For example, if dial points to 9, then the four GPIO lines
connected to the switch will read HLLH(0b'1001 = 9). This value
can be reported as an ABS_* event to the input subsystem.

Bhaktipriya Shridhar 62e5147568 Input: mc13783_ts - remove deprecated create_singletheread_workqueue
The workqueue "workqueue" has a single workitem(&priv->work) and hence
doesn't require ordering. Also, it is not being used on a memory reclaim
path. Hence, the singlethreaded workqueue has been replaced with the use
of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

Workitem is sync cancelled in mc13783_ts_remove() to ensure that there
are no workitems pending when the driver is disconnected.

The new(ish) ft6236 simply re-implements the M09 protocol of the

This commit removes this duplicate driver and adds the i2c ids and
dt compatible string to the edt-ft5x06.c driver to keep compatibility.

This commit also adds the standard touchscreen properties as optional
properties to the edt,ft5x06 binding, these were documented in the
focaltech,ft6236 bindingi, but were missing from the edt,ft5x06 doc.

When the USB wireless adapter is suspended, the controllers
lose their connection. This causes them to start flashing
their LED rings and searching for the wireless adapter
again, wasting the controller's battery power.

Instead, we will tell the controllers to power down when
we suspend. This mirrors the behavior of the controllers
when connected to the console itself and how the official
Xbox One wireless adapter behaves on Windows.

As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.

> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c.  atkbd.c depends on libps2.c because it invokes
> ps2_command().  libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner().  As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)

To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

Markus Elfring 887ec0bfbd Input: synaptics-rmi4 - do not check for NULL when calling of_node_put()
The of_node_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Douglas Anderson 8f97f8e58b Input: cros_ec_keyb - cleanup use of dev
In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was
the EC's dev pointer and not the keyboard's.  Let's clean this up to
make it the keyboard's dev pointer.  This could be useful in future
patches but also has the nice effect of changing a few printouts to
include the name of the keyboard device instead of the EC device, so we
will see:

[    1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14

instead of:

[    1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14

Passes input_id struct to the common probe function for the tsc200x drivers

This allows for the use of the product variable to set the input_dev->name
variable according to the type of touchscreen used. Note that when we
introduced support for TSC2004 we started calling everything TSC200X, so
let's keep this quirk.

Calling of_find_node_by_name() assumes that the caller has incremented

not incrementing the refcount of the of_node which results in the node
being prematurely freed when of_find_node_by_name() calls of_node_put()
on it. Instead use of_get_child_by_name() which does not call put on the

Sinclair Yeh 60842ef812 Input: vmmouse - remove port reservation
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource.  This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.

This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE.  Because of this, VMMOUSE should not try to reserve this port
on its own.

The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs.  It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

Cameron Gutman c7f1429389 Input: xpad - fix oops when attaching an unknown Xbox One gamepad
Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.

This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.

This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.

Martin Kepplinger 1afca2b66a Input: add Pegasus Notetaker tablet driver
This adds a driver for the Pegasus Notetaker Pen. When connected,
this uses the Pen as an input tablet.

This device was sold in various different brandings, for example
 "Pegasus Mobile Notetaker M210",
 "Genie e-note The Notetaker",
 "Staedtler Digital ballpoint pen 990 01",
 "IRISnotes Express" or
 "NEWLink Digital Note Taker".

Here's an example, so that you know what we are talking about:
http://www.genie-online.de/genie-e-note-2/

https://pegatech.blogspot.com/ seems to be a remaining official resource.

This device can also transfer saved (offline recorded handwritten) data and
there are userspace programs that do this, see https://launchpad.net/m210
(Well, alternatively there are really fast scanners out there :)

It's *really* fun to use as an input tablet though! So let's support this
for everybody.

Cameron Gutman 1ff5fa3c67 Input: xpad - prevent spurious input from wired Xbox 360 controllers
After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00

Linus Torvalds ecc5fbd5ef pwm: Changes for v4.7-rc1
This set of changes introduces an atomic API to the PWM subsystem. This
 is influenced by the DRM atomic API that was introduced a while back,
 though it is obviously a lot simpler. The fundamental idea remains the
 same, though: drivers provide a single callback to implement the atomic
 configuration of a PWM channel.
 
 As a side-effect the PWM subsystem gains the ability for initial state
 retrieval, so that the logical state mirrors that of the hardware. Many
 use-cases don't care about this, but for others it is essential.
 
 These new features require changes in all users, which these patches
 take care of. The core is transitioned to use the atomic callback if
 available and provides a fallback mechanism for other drivers.
 
 Changes to transition users and drivers to the atomic API are postponed
 to v4.8.

Javier Martinez Canillas db36ae8516 Input: migor-ts - allow driver to build if COMPILE_TEST is enabled
The driver only has runtime but no build time dependency with SH_MIGOR, so
it can be built for testing purposes if the COMPILE_TEST option is enabled.

This is useful to have more build coverage and make sure that drivers are
not affected by changes that could cause build regressions.

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,
   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.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - 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.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

Boris Brezillon ad4e9fec14 input: misc: max77693: Use pwm_get_args() where appropriate
The PWM framework has clarified the concept of reference PWM config (the
platform dependent config retrieved from the DT or the PWM lookup table)
and real PWM state.

Use pwm_get_args() when the PWM user wants to retrieve this reference
config and not the current state.

This is part of the rework allowing the PWM framework to support
hardware readout and expose real PWM state even when the PWM has just
been requested (before the user calls pwm_config/enable/disable()).

commit e7ec014a47 ("Input: twl6040-vibra - update for device tree support")

made the separate vibra DT node to a subnode of the twl6040.

It now calls of_find_node_by_name() to locate the "vibra" subnode.
This function has a side effect to call of_node_put on() for the twl6040
parent node passed in as a parameter. This causes trouble later on.

Solution: we must call of_node_get() before of_find_node_by_name()

Florian Euchner c90a0f08fe Input: cm109 - fix handling of volume and mute buttons
The CM109 driver reported key press events of volume up / down and
record / playback mute buttons, but no release events. Report those events
properly by handling volume and mute keys seperately. For the record and
playback mute buttons, only presses are registered by the CM109, therefore
simulate press-n-release. This fixes the volume control buttons of various
USB headsets.

H. Nikolaus Schaller 28a994fad9 Input: twl6040-vibra - fix atomic schedule panic
commit c6f39257c9 ("mfd: twl6040: Use regmap for register cache")

did remove the private cache for the vibra control registers and replaced
access within twl6040_get_vibralr_status() by calls to regmap. This is OK,
as long as twl6040_get_vibralr_status() uses already cached values or is
not called from interrupt context. But we call this in vibra_play() for
checking that the vibrator is not configured for audio mode.

The result is a "BUG: scheduling while atomic" if the first use of the
twl6040 is a vibra effect, because the first fetch is by reading the
twl6040 registers through (blocking) i2c and not from the cache.

As soon as the regmap has cached the status, further calls are fine.

The solution is to move the condition to the work() function which
runs in context that can block.

The original code returns -EBUSY, but the return value of ->play()
functions is ignored anyways. Hence, we do not loose functionality
by not returning an error but just reporting the issue to INFO loglevel.

says that it switches to use the system workqueue but it did neither

- remove the workqueue struct variable
- replace code to really use the system workqueue

Instead it calls queue_work() on uninitialized info->workqueue.

The result is a NULL pointer dereference in vibra_play().

Stephen Boyd eda5ecc0a6 Input: pmic8xxx-pwrkey - fix algorithm for converting trigger delay
The trigger delay algorithm that converts from microseconds to
the register value looks incorrect. According to most of the PMIC
documentation, the equation is

	delay (Seconds) = (1 / 1024) * 2 ^ (x + 4)

except for one case where the documentation looks to have a
formatting issue and the equation looks like

	delay (Seconds) = (1 / 1024) * 2 x + 4

Most likely this driver was written with the improper
documentation to begin with. According to the downstream sources
the valid delays are from 2 seconds to 1/64 second, and the
latter equation just doesn't make sense for that. Let's fix the
algorithm and the range check to match the documentation and the
downstream sources.

input_unregister_device to run after the haptics device has been
removed, since it is itself a child of the MFD device. The default
of using the haptics device itself as the parent is correct.

This adds the VID/PID combination for the Xbox One version of the Mad
Catz FightStick TE 2.

The functionality that this provides is about on par with what the
Windows drivers for the stick manage to deliver.

What works:
- Digital stick
- 6 main buttons
- Xbox button
- The two buttons on the back
- The locking buttons (preventing accidental Xbox button press)

What doesn't work:
- Two of the main buttons (don't work on Windows either)
- The "Haptic" button setting does not have an effect (not sure if it
  works on Windows)

I added the MAP_TRIGGERS_TO_BUTTONS option but in my (limited) testing
there was no practical difference with or without. The FightStick does
not have triggers though so adding it makes sense.

Synaptics uses the Register Mapped Interface (RMI) protocol as a
communications interface for their devices. This driver adds the core
functionality needed to interface with RMI4 devices.

RMI devices can be connected to the host via several transport protocols
and can supports a wide variety of functionality defined by RMI functions.
Support for transport protocols and RMI functions are implemented in
individual drivers. The RMI4 core driver uses a bus architecture to
facilitate the various combinations of transport and function drivers
needed by a particular device.

The X/Y position measurements read from the controller are interpreted
wrong. The first measurement X+ contains the Y position, and the second

The problem is already known and a swap option has been introduced:
commit 6680884a44 ("Input: ad7879 - add option to correct xy axis")

However, the meaning of the new boolean is inverted since the underlying
values are already swapped. Let ts->swap_xy set to true actually be the

Dudley Du 3cd4786943 Input: cyapa - fix for losing events during device power transitions
When changing the scan rate as part of runtime-resume process we may lose
some of the events, because:

1) for gen3 trackpads, the driver must msleep() some time to ensure that
the device is ready to accept next command;

2) for gen5 and later trackpads, the queue dumping function will simply
ignore the events when waiting for the set power mode command response.

The solution is to keep polling and report those valid events when the set
power mode command is in progress.

Simon Horman 5186b8c41a Input: sh_keysc - remove dependency on SUPERH
A dependency on ARCH_SHMOBILE seems to be the best option for sh_keysc:

* For Super H based SoCs: sh_keysc is used on SH_MIGOR, SH_ECOVEC, SH_KFR2R09,
  SH_7722_SOLUTION_ENGINE, and SH_7724_SOLUTION_ENGINE, which depend on
  either CPU_SUBTYPE_SH7722 or CPU_SUBTYPE_SH7724, and both select
  ARCH_SHMOBILE.

* For ARM Based SoCs: Since the removal of legacy (non-multiplatform) support
  this driver has not been used by any Renesas ARM based SoCs. The Renesas
  ARM based SoCs currently select ARCH_SHMOBILE, however, it is planned
  that this will no longer be the case.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

Arnd Bergmann 7ffae9909b Input: spear-keyboard - use __maybe_unused to hide pm functions
The spear keyboard driver uses #ifdef CONFIG_PM to hide its
power management functions, but then uses references from
SIMPLE_DEV_PM_OPS that are only present if both CONFIG_PM
and CONFIG_PM_SLEEP are set, resulting in a warning about unused
functions:

drivers/input/keyboard/spear-keyboard.c:292:12: error: 'spear_kbd_suspend' defined but not used [-Werror=unused-function]
drivers/input/keyboard/spear-keyboard.c:345:12: error: 'spear_kbd_resume' defined but not used [-Werror=unused-function]

This removes the #ifdef and instead uses a __maybe_unused
annotation.

being needed in built-in mode because the following MODULE_DEVICE_TABLE

Linus Torvalds 6b5a12dbca ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
 and ARMv7 platforms together such that they can all be enabled and
 boot the same kernel. It has been a tremendous amount of cleanup and
 refactoring by a huge number of people, and creation of several new
 (and major) subsystems to better abstract out all the platform details
 in an appropriate manner.
 
 The bulk of this branch is a large patchset from Arnd that brings several
 of the more minor and older platforms we have closer to multiplatform
 support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
 Much of this is moving around header files from old mach directories,
 but there are also some cleanup patches of debug_ll (lowlevel debug
 per-platform options) and other parts.
 
 Linus Walleij also has some patchs to clean up the older ARM Realview
 platforms by finally introducing DT support, and Rob Herring has some
 for ARM Versatile which is now DT-only. Both of these platforms are
 now multiplatform.
 
 Finally, a couple of patches from Russell for Dove PMU, and a fix from
 Valentin Rothberg for Exynos ADC, which were rebased on top of the
 series to avoid conflicts.

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"

Benjamin Tissoires 6544a1df11 Input: elantech - mark protocols v2 and v3 as semi-mt
When using a protocol v2 or v3 hardware, elantech uses the function
elantech_report_semi_mt_data() to report data. This devices are rather
creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid
touch is reported.

Anyway, userspace (libinput) is now confused by these (0,0) touches,
and detect them as palm, and rejects them.

Commit 3c0213d17a ("Input: elantech - fix semi-mt protocol for v3 HW")
was sufficient enough for xf86-input-synaptics and libinput before it has
palm rejection. Now we need to actually tell libinput that this device is
a semi-mt one and it should not rely on the actual values of the 2 touches.

IRQENB_HW_PEN bit is set in irqclr so that all interrupts get cleared
later so let IRQENB_HW_PEN be cleared by that.

Without this patch wakeup events from TSC_ADC do not work because pending

Benjamin Tissoires 052876f8e5 Input: uinput - add new UINPUT_DEV_SETUP and UI_ABS_SETUP ioctl
This adds two new ioctls, UINPUT_DEV_SETUP and UI_ABS_SETUP, that replaces
the old device setup method (by write()'ing "struct uinput_user_dev" to the
node). The old method is not easily extendable and requires huge payloads.
Furthermore, overloading write() without properly versioned objects is
error-prone.

Therefore, we introduce two new ioctls to replace the old method.  These
ioctls support all features of the old method, plus a "resolution" field
for absinfo. Furthermore, it's properly forward-compatible to new ABS codes
and a growing "struct input_absinfo" structure.

UI_ABS_SETUP also allows user-space to skip unknown axes if not set.  There
is no need to copy the whole array temporarily into the kernel, but instead
the caller issues several ioctl where we copy each value manually.

Hans Verkuil df9ecb0cad [media] vb2: drop v4l2_format argument from queue_setup
The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.

After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.

To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

Irina Tirdea 68caf85881 Input: goodix - write configuration data to device
Goodix devices can be configured by writing custom data to the device at
init. The configuration data is read with request_firmware from
"goodix_<id>_cfg.bin", where <id> is the product id read from the device
(e.g.: goodix_911_cfg.bin for Goodix GT911, goodix_9271_cfg.bin for
GT9271).

The configuration information has a specific format described in the Goodix
datasheet. It includes X/Y resolution, maximum supported touch points,
interrupt flags, various sensitivity factors and settings for advanced
features (like gesture recognition).

Before writing the firmware, it is necessary to reset the device. If
the device ACPI/DT information does not declare gpio pins (needed for
reset), writing the firmware will not be available for these devices.

This is based on Goodix datasheets for GT911 and GT9271 and on Goodix

Irina Tirdea ec6e1b4082 Input: goodix - reset device at init
After power on, it is recommended that the driver resets the device.
The reset procedure timing is described in the datasheet and is used
at device init (before writing device configuration) and
for power management. It is a sequence of setting the interrupt
and reset pins high/low at specific timing intervals. This procedure
also includes setting the slave address to the one specified in the
ACPI/device tree.

This is based on Goodix datasheets for GT911 and GT9271 and on Goodix
driver gt9xx.c for Android (publicly available in Android kernel
trees for various devices).

For reset the driver needs to control the interrupt and
reset gpio pins (configured through ACPI/device tree). For devices
that do not have the gpio pins properly declared, the functionality
depending on these pins will not be available, but the device can still
be used with basic functionality.

For both device tree and ACPI, the interrupt gpio pin configuration is
read from the "irq-gpios" property and the reset pin configuration is
read from the "reset-gpios" property. For ACPI 5.1, named properties
can be specified using the _DSD section. This functionality will not be
available for devices that use indexed gpio pins declared in the _CRS
section (we need to provide backward compatibility with devices
that do not support using the interrupt gpio pin as output).

For ACPI, the pins can be specified using ACPI 5.1:

PS/2 protocol is slow, and using it with pass-through port (where we

However, so far we have not see anything but trackpoints or basic PS/2
mice on pass-through ports, so let's limit protocols that we probe there
to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol,
and avoid other extended protocols, such as Synaptics, ALPS, etc.

set_properties argument is "true", like with other protocols.

There is a slight change in behavior to make follow-up patches more
uniform: when we detect Cypress but its initialization fails, instead of
immediately returning PSMOUSE_PS2 protocol we now continue trying
IntelliMouse [Explorer]. Given that Cypress devices only have issue with
Sentelic probes probing Imtellimouse should be safe.

According to xboxdrv userspace driver source code, this packet is only
dumping a serial id and should not be interpreted as joystick events.
This issue can be easily seen with jstest:
$ jstest --event /dev/input/js0

This patch only adds a way to filter out this "serial" packet and as a

design is very similar to the mk712.

This commit adds the support for this IP.

Böszörményi Zoltán 6b0f8f9c52 Input: add eGalaxTouch serial touchscreen driver
There are two EETI touchscreen drivers in the kernel (eeti_ts and
egalax_ts) but both are for I2C-connected panels. This is for a different,
serial and not multi-touch touchscreen panel. The protocol documentation is
at http://www.eeti.com.tw/pdf/Software%20Programming%20Guide_v2.0.pdf

Charlie Mooney 3eab4588c9 Input: elan_i2c - set input device's vendor and product IDs
Previously the "vendor" and "product" IDs for the elan_i2c driver simply
reported 0000.  This patch modifies the elan_i2c driver to include the
Elan vendor ID and the touchpad's product id under
input/input*/{vendor,product}.

Specifically, this is to allow us to apply a generic Elan gestures config
that will apply to all Elan touchpads on ChromeOS.  These configs  match to
input devices in various ways, but one major way is by matching on vendor
ID.  Adding this patch allows the default Elan touchpad config to be
applied to Elan touchpads in this kernel by matching on devices that have
vendor ID 04f3.

Note that product ID is also available via custom sysfs entry "product_id"
as well.

Steve Twiss f889beaaab Input: da9063 - report KEY_POWER instead of KEY_SLEEP during power key-press
Stop reporting KEY_SLEEP for a short key-press and report KEY_POWER instead
This change applies to both DA9063 and DA9062 ONKEY drivers.

A previous application used for testing by the developer required a
KEY_SLEEP and KEY_POWER input_report_key event to distinguish between a
short and long key-press of the power key.  This is not the general
convention and the typical solution is for KEY_POWER to be used in both
cases: suspend and S/W power off.

Javier Martinez Canillas b7d21058b4 Input: atmel_mxt_ts - add maxtouch to I2C table for module autoload
The Atmel maxtouch DT binding documents that the compatible string for
the device is "atmel,maxtouch" and the I2C core always reports a module
alias of the form i2c:alias where alias is the compatible string model:

$ grep MODALIAS /sys/devices/platform/12e00000.i2c/i2c-8/8-004b/uevent
MODALIAS=i2c:maxtouch

But there isn't maxtouch entry in the I2C device ID table so when the
i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
alias with a module to load:

$ modinfo atmel_mxt_ts | grep alias
alias:          of:N*T*Catmel,maxtouch
alias:          i2c:mXT224
alias:          i2c:atmel_mxt_tp
alias:          i2c:atmel_mxt_ts
alias:          i2c:qt602240_ts

So add the maxtouch entry to the I2C device ID table to allow the module
to be autoloaded when the device is registered via OF.

Sander Vermin bcf5b3deb0 Input: pixcir_i2c - add support for wake and enable gpios
On some devices the wake and enable pins of the pixcir touchscreen
controller are connected to gpios and these must be controlled by the
driver for the device to operate properly.

Peter Hutterer e0361b7017 Input: wacom_w8001 - split the touch and pen devices into two devices
These devices have a pen device and a touch device through the same serial
protocol, split it up into two separate devices like we do for USB Wacom
tablets too.

Userspace already matches on the device name so we can't drop it
completely. Compose the same basename based on capabilities and append the
tool type, leading to a name like "Wacom Serial Penabled 2FG Touchscreen
Pen".

Note that this drops BTN_TOOL_FINGER, it is not needed once the tools
are split out (and a touch device with BTN_TOOL_FINGER is interpreted
as touchpad by most of userspace).

If a device failed at the pen setup and gets a zero reply from the touch
device, we need to return an error. Otherwise we have a device with
nothing but a name and the EV_KEY and EV_ABS bits.
