I do the following (keeped only clock stuff) properties: clocks: items: - description: Bus clock - description: Module clock - description: MBus clock clock-names: items: - const: ahb - const: mod - const: mbus if: properties: compatible: items: const: allwinner,sun50i-h6-crypto then: properties: clocks: minItems: 3 maxItems: 3 clock-names: minItems: 3 maxItems: 3 else: properties: clocks: minItems: 2 maxItems: 2 clock-names: minItems: 2 maxItems: 2 With this, the dtb_check keep complain that a64 have two short clocks.
