1Broadcom Cygnus PCIe PHY
2
3Required properties:
4- compatible: must be "brcm,cygnus-pcie-phy"
5- reg: base address and length of the PCIe PHY block
6- #address-cells: must be 1
7- #size-cells: must be 0
8
9Each PCIe PHY should be represented by a child node
10
11Required properties For the child node:
12- reg: the PHY ID
130 - PCIe RC 0
141 - PCIe RC 1
15- #phy-cells: must be 0
16
17Example:
18	pcie_phy: phy@301d0a0 {
19		compatible = "brcm,cygnus-pcie-phy";
20		reg = <0x0301d0a0 0x14>;
21
22		pcie0_phy: phy@0 {
23			reg = <0>;
24			#phy-cells = <0>;
25		};
26
27		pcie1_phy: phy@1 {
28			reg = <1>;
29			#phy-cells = <0>;
30		};
31	};
