This was an attempt to silence those warnings: From schema: /new_devel/v4l/hikey970/Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml /new_devel/v4l/hikey970/Documentation/devicetree/bindings/pci/intel-gw-pcie.example.dt.yaml: pcie@d0e00000: '#address-cells', '#interrupt-cells', '#size-cells', 'bus-range', 'clocks', 'device_type', 'interrupt-map', 'interrupt-map-mask', 'linux,pci-domain', 'max-link-speed', 'phy-names', 'phys', 'ranges', 'reset-assert-ms', 'resets' do not match any of the regexes: 'pinctrl-[0-9]+' From schema: /new_devel/v4l/hikey970/Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml /new_devel/v4l/hikey970/Documentation/devicetree/bindings/pci/snps,dw-pcie.example.dt.yaml: pcie@dfc00000: '#address-cells', '#interrupt-cells', '#size-cells', 'device_type', 'interrupts', 'ranges' do not match any of the regexes: 'pinctrl-[0-9]+' From schema: /new_devel/v4l/hikey970/Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml Somehow, dtschema is only accepting 'pinctrl-[0-9]+' regex when parsing examples on this file.
