Ray Jui9d030e12015-09-21 10:17:17 -07001Broadcom 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
