1 Broadcom Stingray PCIe PHY
2
3 Required properties:
4 - compatible: must be "brcm,sr-pcie-phy"
5 - reg: base address and length of the PCIe SS register space
6 - brcm,sr-cdru: phandle to the CDRU syscon node
7 - brcm,sr-mhb: phandle to the MHB syscon node
8 - #phy-cells: Must be 1, denotes the PHY index
9
10 For PAXB based root complex, one can have a configuration of up to 8 PHYs
11 PHY index goes from 0 to 7
12
13 For the internal PAXC based root complex, PHY index is always 8
14
15 Example:
16 mhb: syscon@60401000 {
17 compatible = "brcm,sr-mhb", "syscon";
18 reg = <0 0x60401000 0 0x38c>;
19 };
20
21 cdru: syscon@6641d000 {
22 compatible = "brcm,sr-cdru", "syscon";
23 reg = <0 0x6641d000 0 0x400>;
24 };
25
26 pcie_phy: phy@40000000 {
27 compatible = "brcm,sr-pcie-phy";
28 reg = <0 0x40000000 0 0x800>;
29 brcm,sr-cdru = <&cdru>;
30 brcm,sr-mhb = <&mhb>;
31 #phy-cells = <1>;
32 };
