+Broadcom STB USB PHY
+
+Required properties:
+ - compatible: brcm,brcmstb-usb-phy
+ - reg: two offset and length pairs. The second pair specifies optional
+ registers used by some of the SoCs that support USB 3.x
+ - #phy-cells: Shall be 1 as it expects one argument for setting
+ the type of the PHY. Possible values are 0 (1.1 and 2.0),
+ 1 (3.x)
+
+Optional Properties:
+- clocks : clock phandles.
+- clock-names: String, clock name.
+- brcm,ipp: Boolean, Invert Port Power.
+ Possible values are: 0 (Don't invert), 1 (Invert)
+- brcm,ioc: Boolean, Invert Over Current detection.
+ Possible values are: 0 (Don't invert), 1 (Invert)
+- brcm,has-xhci: Boolean indicating an optional 3.x only XHCI controller.
+- brcm,has-xhci-only: Boolean indicating an XHCI controller that supports
+ 1.1, 2.0 and 3.0 devices
+- brcm,device: String, PHY Device mode.
+ Possible values are: off (Host), on (Device), dual (DRD)
+ or typec-pd (Type-C PD control)
+
+Example:
+
+usbphy_0: usb-phy@f0470200 {
+ reg = <0xf0470200 0xb8>,
+ <0xf0471940 0x6c0>;
+ compatible = "brcm,brcmstb-usb-phy";
+ #phy-cells = <1>;
+ brcm,ioc = <1>;
+ brcm,ipp = <1>;
+ brcm,has-xhci;
+ clocks = <&usb20>, <&usb30>;
+ clock-names = "sw_usb", "sw_usb3";
+};
