Thanks, I'll follow the eip93 model. For v5 the compatible becomes:

    compatible:
      items:
        - not: {}
          description: SoC-specific compatible, e.g. vendor,soc-cmh
        - const: rambus,cmh-v1030

and grows a oneOf branch for the concrete "vendor,soc-cmh" once the first
integrating platform is upstreamed. I'll drop the examples block for now,
as you say.

Will do; I'll add to the description:

    Clock and reset are owned by the CMH management host; a node
    describing a non-management host has no clock or reset provider of its
    own, so clocks and reset-gpios are optional.

Thanks,
Alex
