The Rockchip PX30 SoC has a Hantro VPU that features a decoder (VDPU2)
and an encoder (VEPU2). It is similar to the RK3399's VPU but takes an
extra clock (SCLK).

You could make this:

    clock-names:
      minItems: 2
      items:
        - const: aclk
        - const: hclk
        - const: sclk

And then:

allOf:
  - if:
      properties:
        compatible:
          contains:
            const: rockchip,px30-vpu
    then:
      properties:
        clock-names:
          minItems: 3

to make sure each variant has the correct clocks set.

regards
Philipp

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

yamllint warnings/errors:
./Documentation/devicetree/bindings/media/rockchip-vpu.yaml:23:9: [warning] wrong indentation: expected 10 but found 8 (indentation)
./Documentation/devicetree/bindings/media/rockchip-vpu.yaml:47:9: [warning] wrong indentation: expected 10 but found 8 (indentation)
./Documentation/devicetree/bindings/media/rockchip-vpu.yaml:50:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

dtschema/dtc warnings/errors:

See https://patchwork.ozlabs.org/patch/1423300

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.

Thanks for the suggestion! That's a finer grain that my proposal.

Rob, is there a preference for how this case should be handled?
Here, we want to specify an extra clock for the PX30 case.

Cheers,

Paul
