    1 * Amazon Annapurna Labs PCIe host bridge
    2 
    3 Amazon's Annapurna Labs PCIe Host Controller is based on the Synopsys DesignWare
    4 PCI core. It inherits common properties defined in
    5 Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
    6 
    7 Properties 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>
