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>; |
|
}; |
