Broadcom Stingray PCIe PHY
|
|
|
|
Required properties:
|
|
- compatible: must be "brcm,sr-pcie-phy"
|
|
- reg: base address and length of the PCIe SS register space
|
|
- brcm,sr-cdru: phandle to the CDRU syscon node
|
|
- brcm,sr-mhb: phandle to the MHB syscon node
|
|
- #phy-cells: Must be 1, denotes the PHY index
|
|
|
|
For PAXB based root complex, one can have a configuration of up to 8 PHYs
|
|
PHY index goes from 0 to 7
|
|
|
|
For the internal PAXC based root complex, PHY index is always 8
|
|
|
|
Example:
|
|
mhb: syscon@60401000 {
|
|
compatible = "brcm,sr-mhb", "syscon";
|
|
reg = <0 0x60401000 0 0x38c>;
|
|
};
|
|
|
|
cdru: syscon@6641d000 {
|
|
compatible = "brcm,sr-cdru", "syscon";
|
|
reg = <0 0x6641d000 0 0x400>;
|
|
};
|
|
|
|
pcie_phy: phy@40000000 {
|
|
compatible = "brcm,sr-pcie-phy";
|
|
reg = <0 0x40000000 0 0x800>;
|
|
brcm,sr-cdru = <&cdru>;
|
|
brcm,sr-mhb = <&mhb>;
|
|
#phy-cells = <1>;
|
|
};
