Subject: [PATCH] Imports `drivers/input/` changes from lineage-16.0
input: synaptics_dsx_2.6: correct suspend path for Synaptics V2.6 driver
Correct the suspend path for Synaptics V2.6 driver by adding the brackets
in the error path while calling the pinctrl call. This change will make
the driver not go into undesirable path and complete the function calls
necessary for suspend routine.

input: synaptics_dsx_2.6: enable wakeup gesture for synaptics driver
Enable wakeup gesture for Synaptics V2.6 touch driver. Below changes
are added for the same:
- Enable the wakeup gesture as it was disabled by default as a macro.
- Add change to suspend the touch device for FB_BLANK_VSYNC_SUSPEND
fb event, when display goes to dim setting for this event.
- Enable wakeup feature and make irq as wake-able only once while
going suspend or resume.
- Don't put off regulators when wakeup geature is enabled.

input: touchpanel: Fix abnormal crash caused by Synaptics TP
There was a abnormal kernel crash when TP resumes. The root
cause is that the call of reset_device in TP reusme function
may fail sometimes and watchdog's timeout occurred to make
kernel crash. After removing this useless reset-device by
undefine FB_READY_RESET, TP can work normally.

ANDROID: keychord: Check for write data size
keychord driver causes a kernel warning when writing more than
(1 << (MAX_ORDER - 1)) * PAGE_SIZE bytes to /dev/keychord.
In reality writes to this file should be much smaller, so
limiting data size to PAGE_SIZE seems to be appropriate.
This change checks write data size and if it's more than
PAGE_SIZE causes write to fail.

Change-Id: I761518d81d94331a906340d7c989acb391f27ed9
input: tri-state-key: Properly filter out spurious interrupts
All of the three pins used for the tri-state key are falling-edge
sensitive, and their IRQs are properly configured as such; however,
spurious interrupts can easily be reproduced where all of the three pins
are in a high state, causing unwanted notification-mode changes as a result.
Add a filter to IRQ worker in order to block the spurious interrupts.

input: tri-state-key: Rewrite and optimize
A driver for such a simple device shouldn't be so ugly. Clean it up and
optimize it in the process.
Summary of changes:
-Remove unneeded switch device
-Remove unused/unnecessary struct members
-Remove module references (this driver will always be built in)
-Utilize fixed loops and clever logic to eliminate significant amounts of
code duplication
-Remove unused pinctrl code
-Use a threaded interrupt handler
-Process interrupts directly in the threaded interrupt handler (which runs
with realtime priority) rather than a worker
-Read the initial switch state upon init (so userspace gets the correct
switch state upon boot)
-Refactor code wherever possible to make it cleaner
Note that although the procfs naming scheme is non-standard (i.e.
"keyCode_top" instead of "keycode_top"), the old naming scheme is retained
in order to maintain compatibility with userspace.

Signed-off-by: Sultanxda <sultanxda@gmail.com>
input: tri-state-key: Clean up some code styling
Use a macro to store the number of states, reduce the curr_state member in
the struct to uint8_t (since it only needs to contain 3 bits), and use
find_first_zero_bit() instead of a loop to find the first zero bit.

input: tri-state-key: Use ffz() instead of find_first_zero_bit()
find_first_zero_bit() is intended for large bitmaps; ffz() is much faster
when only a single word needs to be searched through.
