From: Yang Xiwen <forbidden405 at outlook.com>

Also rename to hisilicon,inno-usb2-phy.yaml and add this name to
compatible lists.

-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
-
-Example:
-
-perictrl: peripheral-controller at 8a20000 {
-	compatible = "hisilicon,hi3798cv200-perictrl", "simple-mfd";
