Input: snvs_pwrkey - make it depend on ARCH_MXC

2019-05-16T17:40:26+00:00

[ Upstream commit f06eba72274788db6a43012a05a99915c0283aef ]

The SNVS power key is not only used on i.MX6SX and i.MX7D, it is also
used by i.MX6UL and NXP's latest ARMv8 based i.MX8M series SOC. So
update the config dependency to use ARCH_MXC, and add the COMPILE_TEST
too.

Input: snvs_pwrkey - initialize necessary driver data before enabling IRQ

2019-05-08T05:22:58+00:00

commit bf2a7ca39fd3ab47ef71c621a7ee69d1813b1f97 upstream.

SNVS IRQ is requested before necessary driver data initialized,
if there is a pending IRQ during driver probe phase, kernel
NULL pointer panic will occur in IRQ handler. To avoid such
scenario, just initialize necessary driver data before enabling
IRQ. This patch is inspired by NXP's internal kernel tree.

Input: qt2160 - switch to using brightness_set_blocking()

2019-02-11T22:25:31+00:00

Now that LEDs core allows "blocking" flavor of "set brightness" method we
can use it and get rid of private work items.

Input: matrix_keypad - use flush_delayed_work()

2019-02-09T17:00:03+00:00

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: cap11xx - switch to using set_brightness_blocking()

2019-02-09T16:56:56+00:00

Updating LED state requires access to regmap and therefore we may sleep,
so we could not do that directly form set_brightness() method.
Historically we used private work to adjust the brightness, but with the
introduction of set_brightness_blocking() we no longer need it.

As a bonus, not having our own work item means we do not have
use-after-free issue as we neglected to cancel outstanding work on
driver unbind.

Input: snvs_pwrkey - allow selecting driver for i.MX 7D

2019-01-28T19:24:18+00:00

The i.MX SNVS Power Key driver supports the i.MX 7D SoC family too.
Allow to enable the i.MX SNVS Power Key driver even if only i.MX 7D
SoC is selected.
