-* Amazon Annapurna Labs PCIe host bridge
-
-Amazon's Annapurna Labs PCIe Host Controller is based on the Synopsys DesignWare
-PCI core. 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>;
