I'm not so familiar with this format. Do this has "if-then-'else if'-then-else"? I tried below instead of the clocks segment above: =================================== if: properties: compatible: enum: - mediatek,mt6779-smi-common - mediatek,mt8183-smi-common then: properties: clock: items: - description: apb is the clock for setting the register.. - description: smi is the clock for transfer data and command. - description: gals0 is the path0 clock of gals(global async local sync). - description: gals1 is the path1 clock of gals. clock-names: items: - const: apb - const: smi - const: gals0 - const: gals1 else: if: properties: compatible: contains: enum: - mediatek,mt2701-smi-common then: properties: clocks: items: - description: apb is the clock for setting the register. - description: smi is the clock for transfer data and command. - description: async is asynchronous clock, it help transform the smi clock into the emi clock domain. clock-names: items: - const: apb - const: smi - const: async else: properties: clocks: items: - description: apb is the clock for setting the register. - description: smi is the clock for transfer data and command. clock-names: items: - const: apb - const: smi ================================ But I got a warning when dt_binding_check: CHKDT Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.yaml SCHEMA Documentation/devicetree/bindings/processed-schema-examples.yaml DTC Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.example.dt.yaml CHECK Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.example.dt.yaml .../Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.example.dt.yaml: smi@14022000: 'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+' From schema: .../Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.yaml Any suggestion about this?
