+Broadcom Cygnus PCIe PHY
+
+Required properties:
+- compatible: Must be "brcm,cygnus-pcie-phy"
+- reg: base address and length of the CRMU block
+- #phy-cells: must be <2>
+The first cell is the PHY ID:
+0 - PCIe RC 0
+1 - PCIe RC 1
+The second cell is the internal PHY address
+
+Example:
+ phy: phy@0301d0a0 {
+ compatible = "brcm,cygnus-pcie-phy";
+ reg = <0x0301d0a0 0x14>;
+ #phy-cells = <2>;
+ };
+
+ pcie0: pcie@18012000 {
+ ...
+ ...
+ phys = <&phy 0 5>;
+ phy-names = "pcie-phy";
+ };
+
+ pcie1: pcie@18013000 {
+ ...
+ ...
+ phys = <&phy 1 6>;
+ phy-names = "pcie-phy";
+ };
