Input: matrix_keypad - use flush_delayed_work()

2019-03-23T07:18:59+00:00

[ Upstream commit a342083abe576db43594a32d458a61fa81f7cb32 ]

We should be using flush_delayed_work() instead of flush_work() in
matrix_keypad_stop() to ensure that we are not missing work that is
scheduled but not yet put in the workqueue (i.e. its delay timer has not
expired yet).

Input: omap-keypad - fix keyboard debounce configuration

2018-12-21T13:08:48+00:00

[ Upstream commit 6c3516fed7b61a3527459ccfa67fab130d910610 ]

I noticed that the Android v3.0.8 kernel on droid4 is using different
keypad values from the mainline kernel and does not have issues with
keys occasionally being stuck until pressed again. Turns out there was
an earlier patch posted to fix this as "Input: omap-keypad: errata i689:
Correct debounce time", but it was never reposted to fix use macros
for timing calculations.

This updated version is using macros, and also fixes the use of the
input clock rate to use 32768KiHz instead of 32000KiHz. And we want to
use the known good Android kernel values of 3 and 6 instead of 2 and 6
in the earlier patch.

Input: matrix_keypad - fix race when disabling interrupts

2018-03-18T10:15:42+00:00

commit ea4f7bd2aca9f68470e9aac0fc9432fd180b1fe7 upstream.

If matrix_keypad_stop() is executing and the keypad interrupt is triggered,
disable_row_irqs() may be called by both matrix_keypad_interrupt() and
matrix_keypad_stop() at the same time, causing interrupts to be disabled
twice and the keypad being "stuck" after resuming.

Take lock when setting keypad->stopped to ensure that ISR will not race
with matrix_keypad_stop() disabling interrupts.

Input: mpr121 - set missing event capability

2017-11-15T09:04:12+00:00

[ Upstream commit 9723ddc8fe0d76ce41fe0dc16afb241ec7d0a29d ]

This driver reports misc scan input events on the sensor's status
register changes.  But the event capability for them was not set in the
device initialization, so these events were ignored.

This change adds the missing event capability.

Input: mpr121 - handle multiple bits change of status register

2017-11-15T09:04:12+00:00

[ Upstream commit 08fea55e37f58371bffc5336a59e55d1f155955a ]

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.

Commit fe6b0dfaba68 ("Input: tegra-kbc - use reset framework")
accidentally converted _deassert to _assert, so there is no code
to wake up this hardware.

missed releasing keypad_data.
