-Kirin 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/snps,dw-pcie.yaml.
-
-Additional properties are described here:
-
-Required properties
-- compatible:
- "hisilicon,kirin960-pcie"
- "hisilicon,kirin970-pcie"
-- reg: Should contain rc_dbi, apb, config registers location and length.
-- reg-names: Must include the following entries:
- "dbi": controller configuration registers;
- "apb": apb Ctrl register defined by Kirin;
- "config": PCIe configuration space registers.
