+Broadcom Cygnus PCIe PHY
+
+Required properties:
+- compatible: must be "brcm,cygnus-pcie-phy"
+- reg: base address and length of the PCIe PHY block
+- #address-cells: must be 1
+- #size-cells: must be 0
+
+Each PCIe PHY should be represented by a child node
+
+Required properties For the child node:
+- reg: the PHY ID
+0 - PCIe RC 0
+1 - PCIe RC 1
+- #phy-cells: must be 0
+
+Example:
+ pcie_phy: phy@0301d0a0 {
+ compatible = "brcm,cygnus-pcie-phy";
+ reg = <0x0301d0a0 0x14>;
+
+ pcie0_phy: phy@0 {
+ reg = <0>;
+ #phy-cells = <0>;
+ };
+
+ pcie1_phy: phy@1 {
+ reg = <1>;
+ #phy-cells = <0>;
+ };
+ };
+
+ /* users of the PCIe phy */
+
+ pcie0: pcie@18012000 {
+ ...
+ ...
+ phys = <&pcie0_phy>;
+ phy-names = "pcie-phy";
+ };
+
+ pcie1: pcie@18013000 {
+ ...
+ ...
+ phys = <pcie1_phy>;
+ phy-names = "pcie-phy";
+ };
