Subject: [PATCH v8 0/2] Make AUX gpio pin optional for ktd2692

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 the amount of current going through the LED.

Also convert the txt device-tree bindings to yaml.

v2:
- fix the dt_binding_check
v3:
- set the aux_gpio to NULL to avoid passing ERR_PTR as a gpio
v4:
- maintainership -> maintenance (description)
- remove the if (led->aux_gpio)
- use devm_gpiod_get_optional for aux gpio
v5:
- use ret to pass a correct error return code (Christophe)
v6:
- use PTR_ERR properly (when IS_ERR is true) (Christophe)
v6-a:
- ended up being a mess, corrected-v2 should have proper tags now
v7:
- drop the MAINTAINERS part
v8:
- introduce a patch changing dev_err in gpio access to dev_err_probe
