Kernel-4.18.0-80.el8_phy-hi3798cv200-combphy

HiSilicon STB PCIE/SATA/USB3 PHY

Required properties:

• compatible: Should be “hisilicon,hi3798cv200-combphy”
• reg: Should be the address space for COMBPHY configuration and state
  registers in peripheral controller, e.g. PERI_COMBPHY0_CFG and
  PERI_COMBPHY0_STATE for COMBPHY0 Hi3798CV200 SoC.
• #phy-cells: Should be 1. The cell number is used to select the phy mode
  as defined in <dt-bindings/phy/phy.h>.
• clocks: The phandle to clock provider and clock specifier pair.
• resets: The phandle to reset controller and reset specifier pair.

Refer to phy/phy-bindings.txt for the generic PHY binding properties.

Optional properties:

• hisilicon,fixed-mode: If the phy device doesn’t support mode select
  but a fixed mode setting, the property should be present to specify
  the particular mode.
• hisilicon,mode-select-bits: If the phy device support mode select,
  this property should be present to specify the register bits in
  peripheral controller, as a 3 integers tuple:
  .

Notes:

• Between hisilicon,fixed-mode and hisilicon,mode-select-bits, one and only
  one of them should be present.
• The device node should be a child of peripheral controller that contains
  COMBPHY configuration/state and PERI_CTRL register used to select PHY mode.
  Refer to arm/hisilicon/hisilicon.txt for the parent peripheral controller
  bindings.
