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.

gpio-keys input devices created by the soc_button_array driver are
configured with key-codes based on ACPI provided information.
Unfortunately on some tablets this info is wrong, and we need to have
a quirk to fix things up.

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.

The TCA8418 might be used using different interrupt triggers on various
boards. This is not working so far because the current code forces a
falling edge trigger.
The device tree already provides a trigger type, so let's use whatever it
sets up, and since we can be loaded without DT, keep the old behaviour for
the non-DT case.

Using counter based retry loops for peripherals results in the delay
being significantly overrun during high-load situations where delay
functions tend to be vary imprecise and overrun there timeouts. So
condition the termination on the actual condition of 2s for the
re-calibration to have been successful.
As this is a very long delay there is no advantage in using
high-resolution timers thus switching this to msleep().

This driver reports input events on their interrupts which are triggered
by the sensor's status register changes. But only single bit change is
reported in the interrupt handler. So if there are multiple bits are
changed at almost the same time, other press or release events are ignored.
This fixes it by detecting all changed bits in the status register.

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.
