Instead, the widest constraints are added at the top level and constrained by the allOf. If none of the names etc are shared, at least the widest constraints for minItems and maxItems should be able to be here. That said, this patch should be squashed with the patch that actually adds the other device to the binding.

Just to make sure I got it right: clocks: minItems: 3 maxItems: 4 items: - const: aclk - const: hclk ... allOf: ... - if: properties: compatible: contains: const: rockchip,rk3568-vicap then: properties: clocks: - const: aclk - const: hclk - const: dclk - const: iclk Is this the desired way? > That said, this patch should be squashed with the patch that actually > adds the other device to the binding. That can be arranged.

Otherwise ye, on the right track here.
