0001 Broadcom Stingray PCIe PHY
0002
0003 Required properties:
0004 - compatible: must be "brcm,sr-pcie-phy"
0005 - reg: base address and length of the PCIe SS register space
0006 - brcm,sr-cdru: phandle to the CDRU syscon node
0007 - brcm,sr-mhb: phandle to the MHB syscon node
0008 - #phy-cells: Must be 1, denotes the PHY index
0009
0010 For PAXB based root complex, one can have a configuration of up to 8 PHYs
0011 PHY index goes from 0 to 7
0012
0013 For the internal PAXC based root complex, PHY index is always 8
0014
0015 Example:
0016         mhb: syscon@60401000 {
0017                 compatible = "brcm,sr-mhb", "syscon";
0018                 reg = <0 0x60401000 0 0x38c>;
0019         };
0020
0021         cdru: syscon@6641d000 {
0022                 compatible = "brcm,sr-cdru", "syscon";
0023                 reg = <0 0x6641d000 0 0x400>;
0024         };
0025
0026         pcie_phy: phy@40000000 {
0027                 compatible = "brcm,sr-pcie-phy";
0028                 reg = <0 0x40000000 0 0x800>;
0029                 brcm,sr-cdru = <&cdru>;
0030                 brcm,sr-mhb = <&mhb>;
0031                 #phy-cells = <1>;
