* 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/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-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>;

	};
