You still need to keep the CPU specific part here and explain how this
block is going to get used using the other binding you added.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/cpufreq/cpufreq-mediatek-hw.yaml:46:1: [warning] too many blank lines (4 > 1) (empty-lines)

dtschema/dtc warnings/errors:


See https://patchwork.ozlabs.org/patch/1386572

The base for the patch is generally the last rc1. Any dependencies
should be noted.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

OK, will fix this warning in v8.

OK, will add cpu part here in v8.
