Subject: [PATCH V3 4/5] dt-bindings: input: pm8941-pwrkey: Convert pm8941 power key binding to yaml
Convert qcom pm8941 power key binding from .txt to .yaml format.
Signed-off-by: satya priya <skakit@...eaurora.org>
---
Changes in V2:
- Fixed bot errors, took reference from input.yaml for "linux,code"
- Added one complete example for powerkey and resin, and referenced it
in main PON binding.
- Moved this patch to the end of the series.
Changes in V3:
- Moved this patch before PON binding patch.
- As per Rob's comments, added allOf at the beginning of binding.
Added maxItems for interrupts.
- Added 'unevaluatedProperties' instead of 'additionalProperties' as
we are using allOf.
