+Broadcom Stingray USB PHY
+
+Required properties:
+ - compatible : should be one of the listed compatibles
+ - "brcm,sr-usb-combo-phy" is combo PHY has two PHYs, one SS and one HS.
+ - "brcm,sr-usb-hs-phy" is a single HS PHY.
+ - reg: offset and length of the PHY blocks registers
+ - address-cells: should be 1
+ - size-cells: should be 0
+ - #phy-cells:
+ - Must be 1 for brcm,sr-usb-combo-phy as it expects one argument to indicate
+ the PHY number of two PHYs. 0 for HS PHY and 1 for SS PHY.
+ - Must be 0 for brcm,sr-usb-hs-phy.
+
+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>;
+ #phy-cells = <1>;
+ };
+
+ usbphy1: usb-phy@10000 {
+ compatible = "brcm,sr-usb-combo-phy";
+ reg = <0x00010000 0x100>,
+ #address-cells = <1>;
+ #size-cells = <0>;
+ #phy-cells = <1>;
+ };
+
+ usbphy2: usb-phy@20000 {
+ compatible = "brcm,sr-usb-hs-phy";
+ reg = <0x00020000 0x100>,
