Describe the firmware-managed variant of the QCom DesignWare MAC. As the
properties here differ a lot from the HLOS-managed variant, lets put it
in a separate file.

These seem to be a false-positives triggered by modifying the
high-level snps.dwmac.yaml file?

No. You just made 3 power-domains required for everyone.

With a maxItems: 3?

What is the correct approach then?

Bartosz

You have to test without DT_SCHEMA_FILES set so that every example is
tested with every possible schema.
