It inherits common properties defined in Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml. Properties of the host controller node that differ from it are: - compatible: Usage: required Value type: <stringlist> Definition: Value should contain - "amazon,al-alpine-v2-pcie" for alpine_v2 - "amazon,al-alpine-v3-pcie" for alpine_v3 - reg: Usage: required Value type: <prop-encoded-array> Definition: Register ranges as listed in the reg-names property - reg-names: Usage: required Value type: <stringlist> Definition: Must include the following entries - "config" PCIe ECAM space - "controller" AL proprietary registers - "dbi" Designware PCIe registers Example: pcie-external0: pcie@fb600000 { compatible = "amazon,al-alpine-v3-pcie"; reg = <0x0 0xfb600000 0x0 0x00100000 0x0 0xfd800000 0x0 0x00010000 0x0 0xfd810000 0x0 0x00001000>; reg-names = "config", "controller", "dbi"; bus-range = <0 255>; device_type = "pci"; #address-cells = <3>; #size-cells = <2>; #interrupt-cells = <1>; interrupts = <GIC_SPI 49 IRQ_TYPE_LEVEL_HIGH>; interrupt-map-mask = <0x00 0 0 7>; interrupt-map = <0x0000 0 0 1 &gic GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>; /* INTa */ ranges = <0x02000000 0x0 0xc0010000 0x0 0xc0010000 0x0 0x07ff0000>; }; |
