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

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Wasn't this fixed already by Michal?
