Documentation/devicetree/bindings/phy/phy-hi3798cv200-combphy.txt

-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:
-  <register_offset bit_shift bit_mask>.
-
-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.
