* Amlogic G12A USB3 + PCIE Combo PHY binding
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "amlogic,meson-g12a-usb3-pcie-phy"
|
||||
- #phys-cells: must be 1. The cell number is used to select the phy mode
|
||||
as defined in <dt-bindings/phy/phy.h> between PHY_TYPE_USB3 and PHY_TYPE_PCIE
|
||||
- reg: The base address and length of the registers
|
||||
- clocks: a phandle to the 100MHz reference clock of this PHY
|
||||
- clock-names: must be "ref_clk"
|
||||
- resets: phandle to the reset lines for the PHY control
|
||||
- reset-names: must be "phy"
|
||||
|
||||
Example:
|
||||
usb3_pcie_phy: phy@46000 {
|
||||
compatible = "amlogic,g12a-usb3-pcie-phy";
|
||||
reg = <0x0 0x46000 0x0 0x2000>;
|
||||
clocks = <&clkc CLKID_PCIE_PLL>;
|
||||
clock-names = "ref_clk";
|
||||
resets = <&reset RESET_PCIE_PHY>;
|
||||
reset-names = "phy";
|
||||
#phy-cells = <1>;
|
||||
};
