1TI PCI Controllers 2 3PCIe Designware Controller 4 - compatible: Should be "ti,dra7-pcie"" 5 - reg : Two register ranges as listed in the reg-names property 6 - reg-names : The first entry must be "ti-conf" for the TI specific registers 7 The second entry must be "rc-dbics" for the designware pcie 8 registers 9 The third entry must be "config" for the PCIe configuration space 10 - phys : list of PHY specifiers (used by generic PHY framework) 11 - phy-names : must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the 12 number of PHYs as specified in *phys* property. 13 - ti,hwmods : Name of the hwmod associated to the pcie, "pcie<X>", 14 where <X> is the instance number of the pcie from the HW spec. 15 - interrupts : Two interrupt entries must be specified. The first one is for 16 main interrupt line and the second for MSI interrupt line. 17 - #address-cells, 18 #size-cells, 19 #interrupt-cells, 20 device_type, 21 ranges, 22 num-lanes, 23 interrupt-map-mask, 24 interrupt-map : as specified in ../designware-pcie.txt 25 26Optional Property: 27 - gpios : Should be added if a gpio line is required to drive PERST# line 28 29Example: 30axi { 31 compatible = "simple-bus"; 32 #size-cells = <1>; 33 #address-cells = <1>; 34 ranges = <0x51000000 0x51000000 0x3000 35 0x0 0x20000000 0x10000000>; 36 pcie@51000000 { 37 compatible = "ti,dra7-pcie"; 38 reg = <0x51000000 0x2000>, <0x51002000 0x14c>, <0x1000 0x2000>; 39 reg-names = "rc_dbics", "ti_conf", "config"; 40 interrupts = <0 232 0x4>, <0 233 0x4>; 41 #address-cells = <3>; 42 #size-cells = <2>; 43 device_type = "pci"; 44 ranges = <0x81000000 0 0 0x03000 0 0x00010000 45 0x82000000 0 0x20013000 0x13000 0 0xffed000>; 46 #interrupt-cells = <1>; 47 num-lanes = <1>; 48 ti,hwmods = "pcie1"; 49 phys = <&pcie1_phy>; 50 phy-names = "pcie-phy0"; 51 interrupt-map-mask = <0 0 0 7>; 52 interrupt-map = <0 0 0 1 &pcie_intc 1>, 53 <0 0 0 2 &pcie_intc 2>, 54 <0 0 0 3 &pcie_intc 3>, 55 <0 0 0 4 &pcie_intc 4>; 56 pcie_intc: interrupt-controller { 57 interrupt-controller; 58 #address-cells = <0>; 59 #interrupt-cells = <1>; 60 }; 61 }; 62}; 63
