1 Socionext UniPhier PCIe PHY bindings
3 This describes the devicetree bindings for PHY interface built into
4 PCIe controller implemented on Socionext UniPhier SoCs.
7 - compatible: Should contain one of the following:
8 "socionext,uniphier-pro5-pcie-phy" - for Pro5 PHY
9 "socionext,uniphier-ld20-pcie-phy" - for LD20 PHY
10 "socionext,uniphier-pxs3-pcie-phy" - for PXs3 PHY
11 - reg: Specifies offset and length of the register set for the device.
12 - #phy-cells: Must be zero.
13 - clocks: A list of phandles to the clock gate for PCIe glue layer
15 - clock-names: For Pro5 only, should contain the following:
16 "gio", "link" - for Pro5 SoC
17 - resets: A list of phandles to the reset line for PCIe glue layer
19 - reset-names: For Pro5 only, should contain the following:
20 "gio", "link" - for Pro5 SoC
23 - socionext,syscon: A phandle to system control to set configurations
26 Refer to phy/phy-bindings.txt for the generic PHY binding properties.
