acpi_dev_found checks that there is a matching ACPI node, but it
may be disabled (_STA method returns 0) in which case the
soc_button_array driver will not bind to it and axp20x-pek should
handle the power-button.
This commit switches from acpi_dev_found to acpi_dev_present to
avoid not registering an input-dev for the powerbutton when there
is a disabled PNP0C40 device.
The ACPI-6.0 standard defines a standard gpio button device using
the ACPI0011 HID replacing the custom PNP0C40 gpio device, many
newer devices define both PNP0C40 and ACPI0011 devices enabling one
or the other depending on whether the BIOS thinks it is going to boot
Android or Windows.
This commit adds a check for the ACPI0011 device, so that if
either device is present *and* enabled we don't register an input-dev
for the powerbutton.

Commit 9b13a4ca8d ("Input: axp20x-pek - do not register input device
on some systems") added a check for the INTCFD9 ACPI device which also
handles the powerbutton as on some systems the powerbutton is connected
to both the PMIC, handled by axp20x-pek, and to a gpio on the SoC, handled
by soc_button_array which attaches itself to the INTCFD9 ACPI device.
Testing + comparing DSDTs has shown that this only happens on Cherry
Trail devices with an AXP288 PMIC, the AXP288 PMIC is also used on
Bay Trail devices but there the power button is only connected to
the PMIC and not handled by soc_button_array.
This means that the INTCFD9 check has caused a regression on Bay Trail
devices, causing power-button presses to no longer be seen.
This commit fixes this by limiting the check to devices where the ACPI
node for the AXP288 contains a _HRV (hardware revision) attribute with
a value of 3 which indicates we are dealing with a Cherry Trail platform.

Core changes
- Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
This was a much discussed change. It affects use cases where people
write drivers that might or might not be using GPIO resources.
I have decided that this is the lesser evil right now.
- Make gpiod_count() behave consistently across different hardware
descriptions.
- Fix the syntax around open drain/open source to not infer active
high/low semantics.
New drivers
- A new single-register fixed-direction framework driver for hardware
that have lines controlled by a single register that just work in
one direction (out or in), including IRQ support.
- Support the Fintek F71889A GPIO SuperIO controller.

as they provide irqchips, and thus we are progressing on realtime
compliance.
- Use devm_irq_alloc_descs() in a slew of drivers, getting managed

Merge tag 'v4.11-rc5' into next
Sync up with mainline to bring in changes to input subsystem merged
through other trees.
This essentially reverts commit baf28d91e7 ("Input: bma150 - avoid
binding to bma180 if IIO bma180 driver present") and commit ef3714fdbc
("Input: bma150 - extend chip detection for bma180")
Rationale: initially (2012) the GTA04 device using a bma180 chip simply
referenced the bma150 platform driver in its board file [1] which happened
to work in all scenarios that were tested.
When conversion to DT started (2014), we needed to make the driver be still
recognised. Hence we introduced the compatibility to the bma180 chip in
Linux 3.15-rc5 [2] without further checks if it is really 100% compatible.
This worked flawlessly for years with the GTA04 device.
Recently (2016), Hans de Goede pointed out that the chips are not as
similar as they appeared and the driver works with the bma180 for the GTA04
only by good luck. He proposed to remove the bma180 support completely [3],
but we still did need it until we have a replacement. Thus, a conditional
compile was added.
We have now developed a generic iio-input-bridge which works with any 2 or
3 axis iio based accelerometer. It has been tested on GTA04 and Pyra and
works as expected. Therefore we can remove the bma180 support from this
driver completely. User-space API compatibility can be restored by using
the iio-input-bridge.
Maybe it is time to convert the bma150 driver to iio as well and retire the
accelerometer input drivers completely but this is a different story and
task.

Windows 10 tablets with gpio buttons will typically use the ACPI 6.0
Generic Button Device with a HID of ACPI0011 for these buttons.
The ACPI description for these in the ACPI0011 devices _DSD object uses
something resembling HID descriptors, except that instead of indicating
a bit index into a HID input report, the index indicates the _CRS index
for the GPIO.
The use of 1 interrupt per button, some of which need to be wakeup
sources, instead of using input reports makes it impossible to use the
HID subsystem for this.
This really is just another gpio-keys input device with the platform
data described in ACPI, so this commit adds parsing for this new way
to describe gpio-keys to the soc_button_array driver.

On some systems (Intel tablets with axp288 pmic) the powerbutton is
also connected to a gpio pin of the SoC, advertised through the
"INTCFD9" / "PNP0C40" acpi device. This leads to double reporting
of powerbutton events, which is undesirable, so one driver needs
to not report input events in this case.
Since the soc_button_array driver for the "PNP0C40" acpi device
also handles wake from suspend on these tablets and since the
axp20x-pel driver requires relative expensive i2c accrsses,
it is best for the axp20x-pek driver to not register an input device
in this case.
Note that this commit leaves the axp20x-driver bound to the
device, rather then returning -ENODEV, this is done so that the

Calling device_init_wakeup in the remove function is unnecessary since the
device is going away, and thus won't be able to cause any wakeups under any
circumstances. Besides, the driver cleanup code already handles the
necessary cleanup.
Similarly, disabling wakeup in the probe error path is unnecessary, as is
disabling wakeup in the probe function in the first place.

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.

longer. (~20 ms actual sleep for any value given in the 1~20ms range) This

many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work

We were assigning I2C bus controller instead of client as parent device.
Besides being logically wrong, it messed up with devm handling of input
device. As a result we were leaving input device and event node behind
after rmmod-ing the driver, which lead to a kernel oops if one were to
access the event node later.
Let's remove the assignment and rely on devm_input_allocate_device() to
set it up properly for us.

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing

a prefix.

take a specified SoC component and automatically add the name prefix to
the provided pin name.

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.

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.

This driver provides a input driver for the power button on the
HiSi 65xx SoC for boards like HiKey.
This driver was originally by Zhiliang Xue <xuezhiliang@huawei.com>
then basically rewritten by Jorge, but preserving the original
module author credits.

"Just a few more driver fixes; new drivers will be coming in the next
merge window"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: pwm-beeper - fix - scheduling while atomic
Input: xpad - xbox one elite controller support
Input: xpad - add more third-party controllers
Input: xpad - prevent spurious input from wired Xbox 360 controllers
Input: xpad - move pending clear to the correct location
Input: uinput - handle compat ioctl for UI_SET_PHYS
Pwm config may sleep so defer it using a worker.
On a Freescale i.MX53 based board we ran into "BUG: scheduling while
atomic" because input_inject_event locks interrupts, but
imx_pwm_config_v2 sleeps.
Tested on Freescale i.MX53 SoC with 4.6.0.

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.

When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS
ioctl needs to be treated with special care, as it has the pointer
size encoded in the command.
