Rob, As I'm preparing some upstream patches for kirin-pcie driver to support Hikey 970, I opted to try first to convert the existing schema to yaml. It should be noticed that those two patches currently won't pass cleanly with dtbs_check/dt_binding_check. I'm out of ideas about how to fix. It sounds to me that the checking tools are trying to enforce different types of reference types than the ones used by designware drivers.: $ make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 DT_SCHEMA_FILES=Documentation/devicetree/bindings/pci/designware,pcie.yaml dt_binding_check LINT Documentation/devicetree/bindings DTEX Documentation/devicetree/bindings/pci/designware,pcie.example.dts CHKDT Documentation/devicetree/bindings/processed-schema-examples.json SCHEMA Documentation/devicetree/bindings/processed-schema-examples.json DTC Documentation/devicetree/bindings/pci/designware,pcie.example.dt.yaml CHECK Documentation/devicetree/bindings/pci/designware,pcie.example.dt.yaml [[2164260864, 0, 0, 3724541952, 0, 65536, 2181038080, 0, 3493855232, 3493855232, 0, 218103808]] is not of type 'boolean' True was expected [[2164260864, 0, 0, 3724541952, 0, 65536, 2181038080, 0, 3493855232, 3493855232, 0, 218103808]] is not of type 'null' [2164260864, 0, 0, 3724541952, 0, 65536, 2181038080, 0, 3493855232, 3493855232, 0, 218103808] is too long From schema: /home/mchehab/.local/lib/python3.9/site-packages/dtschema/schemas/pci/pci-bus.yaml $ make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 DT_SCHEMA_FILES=Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.yaml dt_binding_check DTEX Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dts DTC Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml CHECK Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml /devel/v4l/hikey970/Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml: pcie@f4000000: 'reset-gpios' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: /devel/v4l/hikey970/Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.yaml /devel/v4l/hikey970/Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml: pcie@f4000000: '#interrupt-cells', 'bus-range', 'clock-names', 'clocks', 'device_type', 'interrupt-map', 'interrupt-map-mask', 'num-lanes', 'ranges' do not match any of the regexes: 'pinctrl-[0-9]+' From schema: /devel/v4l/hikey970/Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.yaml I ran out of ideas about how to solve that. So, I'm posting it as a RFC.
