+Qualcomm Synopsys 28nm Femto phy controller
+===========================================
+
+Synopsys 28nm femto phy controller supports LS/FS/HS usb connectivity on
+Qualcomm chipsets.
+
+Required properties:
+
+- compatible:
+ Value type: <string>
+ Definition: Should contain "qcom,qcs404-usb-hsphy".
+
+- 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
+ sleep clocks.
+
+- clock-names:
+ Value type: <string>
+ Definition: Names of the clocks in 1-1 correspondence with the "clocks"
+ property. Must contain "ref", "phy" and "sleep".
+
+- resets:
+ Value type: <prop-encoded-array>
+ Definition: See reset.txt section "consumers". PHY reset specifiers
+ for phy core and POR resets.
+
+- reset-names:
+ Value type: <string>
+ Definition: Names of the resets in 1-1 correspondence with the "resets"
+ property. Must contain "phy" and "por".
+
+- 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.
+
+- vdda3p3-supply:
+ Value type: <phandle>
+ Definition: phandle to the regulator 3.3V 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:
+
+- The link to the USB connector should be modeled using the OF graph bindings
+ specified in bindings/graph.txt.
+
+Example:
+
+ phy@7a000 {
+ compatible = "qcom,qcs404-usb-hsphy";
+ reg = <0x7a000 0x200>;
+ #phy-cells = <0>;
+ clocks = <&rpmcc RPM_SMD_LN_BB_CLK>,
+ <&gcc GCC_USB_HS_PHY_CFG_AHB_CLK>,
+ <&gcc GCC_USB2A_PHY_SLEEP_CLK>;
+ clock-names = "ref", "phy", "sleep";
+ resets = <&gcc GCC_USB_HS_PHY_CFG_AHB_BCR>,
+ <&gcc GCC_USB2A_PHY_BCR>;
+ reset-names = "phy", "por";
+ vdd-supply = <&vreg_l4_1p2>;
+ vdda1p8-supply = <&vreg_l5_1p8>;
+ vdda3p3-supply = <&vreg_l12_3p3>;
+ qcom,vdd-voltage-level = <0 1144000 1200000>;
+
+ port {
+ ep_usb_phy: endpoint {
+ remote-endpoint = <&ep_usb_con>;
+ };
+ };
+ };
