Convert input/qcom,pm8xxx-pwrkey.txt to YAML, and take in account that
the PM8921 pwrkey compatible is used as fallback for the PM8018 pwrkey.

You miss diffstat... but I guess it's result of b4?

Yep, I'll update with last release to get it back.

Keep only Bjorn. Andy did not review much for some time.

Ack

In such case better to drop maxItems and description and write it:

items:
- description: key release interrupt
- description: key press interrupt

(maybe even the "interrupt" word could be skipped...)

Ack, will do that without the interrupt word

+
+ pwrkey@1c {

Messed up indentation. For entire DTS example keep 2 or 4 spaces.

+ reg = <0x1c>;
+ interrupt-parent = <&pmicint>;
+ interrupts = <50 1>, <51 1>;

Use defines for interrupt flags.

Will fix the example,
