The Xbox One S requires an ack to its mode button report, otherwise it
continuously retransmits the report. This makes the mode button appear to
be stuck down after it is pressed for the first time.

If device is supposed to send absolute events (i.e. EV_ABS bit is set in
dev->evbit) but dev->absinfo is not allocated, then the driver has done
something wrong, and we should not register such device. Otherwise we'll
crash later, when driver tries to send absolute event.

Let's drop legacy platform data support (there are no users in mainline)
and switch to using generic device properties, which will make the driver
simpler (non-OF boards can use property sets to describe hardware).

Instead of being OF-specific, let's switch to using generic device
properties, which will make this code usable on ACPI, device tree and

As part of the change let's rename matrix_keypad_parse_of_params() to
matrix_keypad_parse_properties().

The MPU3050 driver in the input subsystem has been superseded by a proper
IIO driver found in drivers/iio/gyro/mpu3050*.
Patches have been submitted to remove all defconfig and related references
to the old driver and replace this input driver with the IIO driver.
So delete the input driver. Input was never a good fit for sensors anyway.

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.
