cee3d8ccbe Input: ambakmi - fix system PM by converting to modern callbacks
The legacy system PM support has long time ago been dropped from the
AMBA bus. Align to that by converting to the modern system PM
callbacks.

Fixes: 26825cfd90 (ARM: 7914/1: amba: Drop legacy PM support ...)

e1443d2849 Input: i8042 - add unmask_kbd_data option
A big problem with the current i8042 debugging option is that it outputs
data going to and from the keyboard by default. As a result, many dmesg
logs uploaded by users will unintentionally contain sensitive information
such as their password, as such it's probably a good idea not to output
data coming from the keyboard unless specifically enabled by the user.

339d6b88e8 Input: wdt87xx_i2c - change the sleep time to 2500ms after the sw reset
The original wait time was 200ms which was enough for the firmware to
finish loading and boot. After that the firmware will perform
initialization and touch calibration, which will take about 1.1 second. The
touch calibration will change controller frequency to scan at the most
optimal frequency and during calibration/frequency switching process we may
run into i2c data errors. To avoid them we extend the sleep to 2500ms after
issuing the sw reset.

eeeee40fcc Input: axp20x-pek - fix reporting button state as inverted
Currently we are reporting the button state as inverted on all boards with
an axp209 pmic, tested on a ba10-tvbox, bananapi, bananapro, cubietruck and
utoo-p66 tablet.

The axp209 datasheet clearly states that the power button must be connected
between the PWRON key and ground. Which means that on a press we will get
a falling edge (dbf) irq not a rising one, and likewise on release we will
get a rising edge (dbr) irq, not a falling one.

This commit swaps the check for the 2 irqs fixing the inverted reporting of
the power button state.

which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for
output. Simplify drivers accordingly.

Note that in the case of the drv260x driver error checking is more
strict now because -ENOSYS is reported to the caller now. But this
should only be returned if GPIOLIB is disabled which shouldn't happen as
the driver depends on GPIOLIB.

f60c8ba77d Input: export LEDs as class devices in sysfs
This change creates a new input handler called "leds" that exports LEDs on input
devices as standard LED class devices in sysfs and allows controlling their
state via sysfs or via any of the standard LED triggers. This allows to
re-purpose and reassign LDEs on the keyboards to represent states other
than the standard keyboard states (CapsLock, NumLock, etc).

The old API of controlling input LEDs by writing into /dev/input/eventX
devices is still present and will take precedence over accessing via LEDs
subsystem (i.e. it may override state set by a trigger). If input device is
"grabbed" then requests coming through LED subsystem will be ignored.

gcc-5 defaults to gnu11 which used c99 inline semantics in c99 'inline' is
not externally visible unlike gnu89, therefore we use 'static inline' which
has same semantics between gnu89 and c99

3a38958d24 Input: adxl34x - add OF match support
The I2C subsystem can match devices without explicit OF support based on
the part of their compatible property after the comma. However, this
mechanism uses the first compatible value only. For adxl34x OF device
nodes the compatible property will contain the more specific
"adi,adxl345" or "adi,adxl346" value first. This prevents the device
node from being matched with the adxl34x driver.

Fix this by adding an OF match table with an "adi,adxl345" compatible
entry. There's no need to add the "adi,adxl346" entry as the ADXL346 is
backward-compatible with the ADXL345 with differences handled by runtime
detection of the device model.
