Socionext UniPhier PCIe PHY bindings
This describes the devicetree bindings for PHY interface built into
PCIe controller implemented on Socionext UniPhier SoCs.
Required properties:
- compatible: Should contain one of the following:
"socionext,uniphier-ld20-pcie-phy" - for LD20 PHY
"socionext,uniphier-pxs3-pcie-phy" - for PXs3 PHY
- reg: Specifies offset and length of the register set for the device.
- #phy-cells: Must be zero.
- clocks: A phandle to the clock gate for PCIe glue layer including
this phy.
- resets: A phandle to the reset line for PCIe glue layer including
this phy.
Optional properties:
- socionext,syscon: A phandle to system control to set configurations
for phy.
Refer to phy/phy-bindings.txt for the generic PHY binding properties.
Example:
pcie_phy: phy@66038000 {
compatible = "socionext,uniphier-ld20-pcie-phy";
reg = <0x66038000 0x4000>;
#phy-cells = <0>;
clocks = <&sys_clk 24>;
resets = <&sys_rst 24>;
socionext,syscon = <&soc_glue>;
};
