+Qualcomm Synopsys 1.0.0 SS phy controller
+===========================================
+
+Qualcomm 1.0.0 SS phy controller supports SuperSpeed USB connectivity on
+some Qualcomm platforms.
+
+Required properties:
+
+- compatible:
+ Value type: <string>
+ Definition: Should contain "qcom,snps-usb-ssphy".
+
+- reg:
+ Value type: <prop-encoded-array>
+ Definition: USB PHY base address and length of the register map.
+
+- #phy-cells:
+ Value type: <u32>
+ Definition: Should be 0. See phy/phy-bindings.txt for details.
+
+- clocks:
+ Value type: <prop-encoded-array>
+ Definition: See clock-bindings.txt section "consumers". List of
+ three clock specifiers for reference, phy core and
+ pipe clocks.
+
+- clock-names:
+ Value type: <string>
+ Definition: Names of the clocks in 1-1 correspondence with the "clocks"
+ property. Must contain "ref", "phy" and "pipe".
+
+- vdd-supply:
+ Value type: <phandle>
+ Definition: phandle to the regulator VDD supply node.
+
+- vdda1p8-supply:
+ Value type: <phandle>
+ Definition: phandle to the regulator 1.8V supply node.
+
+Optional properties:
+
+- resets:
+ Value type: <prop-encoded-array>
+ Definition: See reset.txt section "consumers". Specifiers for COM and
+ PHY resets.
+
+- reset-names:
+ Value type: <string>
+ Definition: Names of the resets in 1-1 correspondence with the "resets"
+ property. Must contain "com" and "phy" if the property is
+ specified.
+
+Required child nodes:
+
+- usb connector node as defined in bindings/connector/usb-connector.txt
+ containing the property vbus-supply.
+
+Example:
+
+usb3_phy: usb3-phy@78000 {
+ compatible = "qcom,snps-usb-ssphy";
+ reg = <0x78000 0x400>;
+ #phy-cells = <0>;
+ clocks = <&rpmcc RPM_SMD_LN_BB_CLK>,
+ <&gcc GCC_USB_HS_PHY_CFG_AHB_CLK>,
+ <&gcc GCC_USB3_PHY_PIPE_CLK>;
+ clock-names = "ref", "phy", "pipe";
+ resets = <&gcc GCC_USB3_PHY_BCR>,
+ <&gcc GCC_USB3PHY_PHY_BCR>;
+ reset-names = "com", "phy";
+ vdd-supply = <&vreg_l3_1p05>;
+ vdda1p8-supply = <&vreg_l5_1p8>;
+ usb3_c_connector: usb3-c-connector {
+ compatible = "usb-c-connector";
+ label = "USB-C";
+ type = "micro";
+ vbus-supply = <&usb3_vbus_reg>;
+ };
+};
