3Amazon's Annapurna Labs PCIe Host Controller is based on the Synopsys DesignWare
4PCI core. It inherits common properties defined in
5Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.

7Properties of the host controller node that differ from it are:
8
9- compatible:
10	Usage: required
11	Value type: <stringlist>
12	Definition: Value should contain
13			- "amazon,al-alpine-v2-pcie" for alpine_v2
14			- "amazon,al-alpine-v3-pcie" for alpine_v3
15
16- reg:
17	Usage: required
18	Value type: <prop-encoded-array>
19	Definition: Register ranges as listed in the reg-names property
20
21- reg-names:
22	Usage: required
23	Value type: <stringlist>
24	Definition: Must include the following entries
25			- "config"	PCIe ECAM space
26			- "controller"	AL proprietary registers
27			- "dbi"		Designware PCIe registers
