Kernel-4.18.0-80.el8_phy-hisi-inno-usb2

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 suppports 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
