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>;
|
|
};
|
|
};
|
|
|
