* ThunderX PEM PCIe host controller Firmware-initialized PCI host controller found on some Cavium ThunderX processors. The properties and their meanings are identical to those described in host-generic-pci.txt except as listed below. Properties of the host controller node that differ from host-generic-pci.txt: - compatible : Must be "cavium,pci-host-thunder-pem" - reg : Two entries: First the configuration space for down stream devices base address and size, as accessed from the parent bus. Second, the register bank of the PEM device PCIe bridge. Example: pci@87e0,c2000000 { compatible = "cavium,pci-host-thunder-pem"; device_type = "pci"; msi-parent = <&its>; msi-map = <0 &its 0x10000 0x10000>; bus-range = <0x8f 0xc7>; #size-cells = <2>; #address-cells = <3>; reg = <0x8880 0x8f000000 0x0 0x39000000>, /* Configuration space */ <0x87e0 0xc2000000 0x0 0x00010000>; /* PEM space */ ranges = <0x01000000 0x00 0x00020000 0x88b0 0x00020000 0x00 0x00010000>, /* I/O */ <0x03000000 0x00 0x10000000 0x8890 0x10000000 0x0f 0xf0000000>, /* mem64 */ <0x43000000 0x10 0x00000000 0x88a0 0x00000000 0x10 0x00000000>, /* mem64-pref */ <0x03000000 0x87e0 0xc2f00000 0x87e0 0xc2000000 0x00 0x00100000>; /* mem64 PEM BAR4 */ #interrupt-cells = <1>; interrupt-map-mask = <0 0 0 7>; interrupt-map = <0 0 0 1 &gic0 0 0 0 24 4>, /* INTA */ <0 0 0 2 &gic0 0 0 0 25 4>, /* INTB */ <0 0 0 3 &gic0 0 0 0 26 4>, /* INTC */ <0 0 0 4 &gic0 0 0 0 27 4>; /* INTD */ };
