A nit, subject: drop second/last, redundant "binding for". The
"dt-bindings" prefix is already stating that these are bindings.

Here and subject: drop driver. Bindings are for hardware.

Neither commit nor bindings in description: field explain what is this
hardware.

Drop bindings. If you tested your code, you would see a warning, so:

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

What's this? Part of SoC? Then the compatible is not correct.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

Indentation is messed up.
