Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Use consistent naming. If other is "-clk" this should be as well.

Isn't this located on the board? Physically on the board?

These are not allowed on their own. Your patchset is really not tested
