So this is v12 and still no tested?

A nit, subject: drop second/last, redundant "yaml devicetree indings".
The "dt-bindings" prefix is already stating that these are bindings.
Basically three words bringing zero information.

Do not need '|-' unless you need to preserve formatting.

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.

Missing blank line

Drop clock-names, not really useful for one entry.

Keep the same order as listed in properties:
