Please run scripts/checkpatch.pl and fix reported warnings.

Applies to all your patches. Also test them... I have doubts that you
tested if you actually ignored checkpatch :/

Missing description.

Drop quotes (applies to all your patches)

Missing SoC specific compatible.

Missing additionalProperties. sorry, start from scratch from some
existing recent bindings or better example-schema.

What is this? How do you expect it to apply? Can you try by yourself?
