+Broadcom Stingray USB PHY
+
+Required properties:
+ - compatible : should be one of the listed compatibles
+	- "brcm,sr-usb-combo-phy" is a combo PHY has one SS PHY and one HS PHY.
+	- "brcm,sr-usb-hs-phy" has a single HS PHY.
+ - reg: offset and length of the PHY blocks registers
+ - address-cells: should be 1
+ - size-cells: should be 0
+
+Sub-nodes:
+  brcm,sr-usb-combo-phy have two sub-nodes for one SS PHY and one HS PHY.
+
+Sub-nodes required properties:
+ - reg: required for brcm,sr-usb-phy model PHY.
+	reg value 0 is HS PHY and 1 is SS PHY.
+ - phy-cells: generic PHY binding; must be 0
+
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+Example:
+	usbphy0: usb-phy@0 {
+		compatible = "brcm,sr-usb-combo-phy";
+		reg = <0x00000000 0x100>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		usb0_phy0: phy@0 {
+			reg = <0>;
+			#phy-cells = <0>;
+		};
+
+		usb0_phy1: phy@1 {
+			reg = <1>;
+			#phy-cells = <0>;
+		};
+	};
+
+	usbphy1: usb-phy@10000 {
+		compatible = "brcm,sr-usb-combo-phy";
+		reg = <0x00010000 0x100>,
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		usb1_phy0: phy@0 {
+			reg = <0>;
+			#phy-cells = <0>;
+		};
+
+		usb1_phy1: phy@1 {
+			reg = <1>;
+			#phy-cells = <0>;
+		};
+	};
+
+	usbphy2: usb-phy@20000 {
+		compatible = "brcm,sr-usb-hs-phy";
+		reg = <0x00020000 0x100>,
+		#address-cells = <1>;
