+Device tree bindings for HiSilicon INNO USB2 PHY
+
+Required properties:
+- compatible: Should be one of the following strings:
+ "hisilicon,inno-usb2-phy",
+ "hisilicon,hi3798cv200-usb2-phy".
+- reg: Should be the address space for PHY configuration register in peripheral
+ controller, e.g. PERI_USB0 for USB 2.0 PHY01 on Hi3798CV200 SoC.
+- clocks: The phandle and clock specifier pair for INNO USB2 PHY device
+ reference clock.
+- resets: The phandle and reset specifier pair for INNO USB2 PHY device reset
+ signal.
+- #address-cells: Must be 1.
+- #size-cells: Must be 0.
+
+The INNO USB2 PHY device should be a child node of peripheral controller that
+contains the PHY configuration register, and each device supports up to 2 PHY
+ports which are represented as child nodes of INNO USB2 PHY device.
+
+Required properties for PHY port node:
+- reg: The PHY port instance number.
+- #phy-cells: Defined by generic PHY bindings. Must be 0.
+- resets: The phandle and reset specifier pair for PHY port reset signal.
+
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
