+Qualcomm Synopsys 1.0.0 SS phy controller
+===========================================
+
+Synopsys 1.0.0 ss phy controller supports SS usb connectivity on Qualcomm
+chipsets
+
+Required properties:
+
+- compatible:
+ Value type: <string>
+ Definition: Should contain "qcom,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.
+
+- qcom,vdd-voltage-level:
+ Value type: <prop-array>
+ Definition: This is a list of three integer values <no min max> where
+ each value corresponding to voltage corner in uV.
+
+Optional child nodes:
+
+- vbus-supply:
+ Value type: <phandle>
+ Definition: phandle to the VBUS supply node.
+
+- resets:
+ Value type: <prop-encoded-array>
+ Definition: See reset.txt section "consumers". PHY reset specifiers
+ for phy core and COR resets.
+
+- reset-names:
+ Value type: <string>
+ Definition: Names of the resets in 1-1 correspondence with the "resets"
+ property. Must contain "com" and "phy".
+
+Example:
+
+usb3_phy: phy@78000 {
+ compatible = "qcom,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>;
+ vbus-supply = <&usb3_vbus_reg>;
+ qcom,vdd-voltage-level = <0 1050000 1050000>;
+};
