-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-pro5-pcie-phy" - for Pro5 PHY
- "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 list of phandles to the clock gate for PCIe glue layer
- including this phy.
-- clock-names: For Pro5 only, should contain the following:
- "gio", "link" - for Pro5 SoC
-- resets: A list of phandles to the reset line for PCIe glue layer
- including this phy.
-- reset-names: For Pro5 only, should contain the following:
- "gio", "link" - for Pro5 SoC
-
-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@...38000 {
- compatible = "socionext,uniphier-ld20-pcie-phy";
- reg = <0x66038000 0x4000>;
- #phy-cells = <0>;
- clocks = <&sys_clk 24>;
- resets = <&sys_rst 24>;
- socionext,syscon = <&soc_glue>;
- };
