After some test, your 1st suggestion works.

The infinite error is introduced from my changes and affect the result of power/renesas,sysc-
rmobile.yaml. The 'additionalProperties' being defined as a DT property is the root of this error.
After fix the indentation, the error is gone.

I'll update the yaml as your 1st suggestion in next version.

Thanks,
TingHan
