That can be simplified to:

        clock-names:
          minItems: 1
          maxItems: 3
          uniqueItems: true
          items:
            - const: core
            - enum: [ clkh, cd ]
            - const: cd

But shouldn't the clkh case be restricted to "renesas,rcar-gen3-sdhi"?

Gr{oetje,eeting}s,

OK, nice.

I don't think so because I assume all following generations will have
clkh as well.

All the best,

My issue is that the _previous_ generations (e.g. SH/R-Mobile and
RZ/A[12]) do not have it.

R-Car Gen2 has SDH clocks and the clock driver implements them,
but they are always disabled, as there are no users.
