Bindings are for hardware, not driver. This suggests it is not suitable
for bindings at all.

Again driver :/

Drop quotes.

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.

Describe hardware, not driver.

Again, driver, so not suitable for DTS and bindings.
