[PATCH v3 0/2] Make AUX gpio pin optional for ktd2692

From: Markuss Broks
Date: Thu Apr 07 2022 - 07:51:40 EST


Some appliances of ktd2692 don't have the AUX pin connected to
a GPIO. Specifically, Samsung Galaxy J5 (2015), which uses ktd2692
for driving the front flash LED, has the pin not connected anywhere on
schematics. Make specifying the AUX pin optional, since it is additional
functionality and only affects amount of current going through the LED.

Also convert the txt device-tree bindings to yaml and pick up maintainership
over the yaml binding and the driver itself.

v2:
- fix the dt_binding_check
v3:
- set the aux_gpio to NULL to avoid passing ERR_PTR as a gpio
