1Device tree bindings for HiSilicon INNO USB2 PHY
2
3Required properties:
4- compatible: Should be one of the following strings:
5	"hisilicon,inno-usb2-phy",
6	"hisilicon,hi3798cv200-usb2-phy".
7- reg: Should be the address space for PHY configuration register in peripheral
8  controller, e.g. PERI_USB0 for USB 2.0 PHY01 on Hi3798CV200 SoC.
9- clocks: The phandle and clock specifier pair for INNO USB2 PHY device
10  reference clock.
11- resets: The phandle and reset specifier pair for INNO USB2 PHY device reset
12  signal.
13- #address-cells: Must be 1.
14- #size-cells: Must be 0.
15
16The INNO USB2 PHY device should be a child node of peripheral controller that
17contains the PHY configuration register, and each device supports up to 2 PHY
18ports which are represented as child nodes of INNO USB2 PHY device.
19
20Required properties for PHY port node:
21- reg: The PHY port instance number.
22- #phy-cells: Defined by generic PHY bindings.  Must be 0.
23- resets: The phandle and reset specifier pair for PHY port reset signal.
