Don't need these. Have moved to qcom,sc8280xp-qmp-usb3-uni-phy.yaml specification instead of qcom,msm8996-qmp-usb3-phy.yaml.

Please run `make > dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst > for instructions). Have addressed these and have created a new patch. Will post it shortly. IPQ9574 doesn't have any power domains, hence don't have power-domains entry in the DT node. make dtbs_check is giving the following messages hope that is ok /local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: phy@7d000: 'power-domains' is a required property From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-usb3-uni-phy.yaml /local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: usb@8a00000: 'power-domains' is a required property From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/usb/qcom,dwc3.yaml > > > + }; > > + > > pcie0_phy: phy@84000 { > > compatible = "qcom,ipq9574-qmp-gen3x1-pcie-phy"; > > reg = <0x00084000 0x1bc>; /* Serdes PLL */ > > @@ -436,6 +475,50 @@ > > status = "disabled"; > > }; > > > > + usb3: usb3@8a00000 { > > usb@ Will fix. > > + compatible = "qcom,ipq9574-dwc3", "qcom,dwc3"; > > + reg = <0x08af8800 0x400>; > > + #address-cells = <1>; > > + #size-cells = <1>; > > + ranges; > > > > > + > > + clocks = <&gcc GCC_SNOC_USB_CLK>, > > + <&gcc GCC_ANOC_USB_AXI_CLK>, > > + <&gcc GCC_USB0_MASTER_CLK>, > > + <&gcc GCC_USB0_SLEEP_CLK>, > > + <&gcc GCC_USB0_MOCK_UTMI_CLK>; > > + > > + clock-names = "sys_noc_axi", > > + "anoc_axi", > > + "master", > > + "sleep", > > + "mock_utmi"; > > + > > + assigned-clocks = <&gcc GCC_USB0_MASTER_CLK>, > > + <&gcc GCC_USB0_MOCK_UTMI_CLK>; > > + assigned-clock-rates = <200000000>, > > + <24000000>; > > + > > + resets = <&gcc GCC_USB_BCR>; > > + status = "disabled"; > > + > > + dwc_0: usb@8a00000 { > > + compatible = "snps,dwc3"; > > + reg = <0x8a00000 0xcd00>; > > + clocks = <&gcc GCC_USB0_MOCK_UTMI_CLK>; > > + clock-names = "ref"; > > + interrupts = ; > > + phys = <&qusb_phy_0>, <&ssphy_0>; > > + phy-names = "usb2-phy", "usb3-phy"; > > + tx-fifo-resize; > > + snps,is-utmi-l1-suspend; > > + snps,hird-threshold = /bits/ 8 <0x0>; > > + snps,dis_u2_susphy_quirk; > > + snps,dis_u3_susphy_quirk; > > + dr_mode = "host"; > > Are you saying that peripheral mode cannot work on this USB controller? > Never?
