1Broadcom Stingray PCIe PHY 2 3Required 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 10For PAXB based root complex, one can have a configuration of up to 8 PHYs 11PHY index goes from 0 to 7 12 13For the internal PAXC based root complex, PHY index is always 8 14 15Example: 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 }; 33 34 /* users of the PCIe PHY */ 35 36 pcie0: pcie@48000000 { 37 ... 38 ... 39 phys = <&pcie_phy 0>; 40 phy-names = "pcie-phy"; 41 };
