+* Amazon Annapurna Labs PCIe host bridge
+
+Amazon's Annapurna Labs PCIe Host Controller is based on the Synopsys DesignWare
+PCI core.
+It shares common functions with the PCIe DesignWare core driver and inherits
+common properties defined in Documentation/devicetree/bindings/pci/designware-pcie.txt.
+Properties of the host controller node that differ from it are:
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: Value should contain
+ - "amazon,al-pcie"
+
+- 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-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>;
+ };
