   1 Broadcom Cygnus PCIe PHY
   2
   3 Required 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
   9 Each PCIe PHY should be represented by a child node
  10
  11 Required properties For the child node:
  12 - reg: the PHY ID
  13 0 - PCIe RC 0
  14 1 - PCIe RC 1
  15 - #phy-cells: must be 0
  16
  17 Example:
  18         pcie_phy: phy@0301d0a0 {
  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>;
