[PATCH v2 1/2] dt-bindings: input: Convert mtk-pmic-keys to DT schema

[PATCH v2 1/2] dt-bindings: input: Convert mtk-pmic-keys to DT schema
Posted by AngeloGioacchino Del Regno 2 years, 1 month ago 
Convert the mtk-pmic-keys to DT schema format.

The old binding was missing documentation for key press/release
interrupts, even though it was supported in hardware and driver,
so support for the same was added during the conversion.

Thank you for doing this. I started this but it seemed you were faster
than me :)
