-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@...d0a0 {
- compatible = "brcm,cygnus-pcie-phy";
- reg = <0x0301d0a0 0x14>;
-
- pcie0_phy: phy@0 {
