      1Amlogic Meson AXG DWC PCIE SoC controller
      2
      3Amlogic Meson PCIe host controller is based on the Synopsys DesignWare PCI core.
      4It shares common functions with the PCIe DesignWare core driver and
      5inherits common properties defined in
      6Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
      7
      8Additional properties are described here:
      9
     10Required properties:
     11- compatible:
     12	should contain :
     13	- "amlogic,axg-pcie" for AXG SoC Family
     14	- "amlogic,g12a-pcie" for G12A SoC Family
     15	to identify the core.
     16- reg:
     17	should contain the configuration address space.
     18- reg-names: Must be
     19	- "elbi"	External local bus interface registers
     20	- "cfg"		Meson specific registers
     21	- "config"	PCIe configuration space
     22- reset-gpios: The GPIO to generate PCIe PERST# assert and deassert signal.
     23- clocks: Must contain an entry for each entry in clock-names.
     24- clock-names: Must include the following entries:
     25	- "pclk"       PCIe GEN 100M PLL clock
     26	- "port"       PCIe_x(A or B) RC clock gate
     27	- "general"    PCIe Phy clock
     28- resets: phandle to the reset lines.
     29- reset-names: must contain "port" and "apb"
     30       - "port"        Port A or B reset
     31       - "apb"         Share APB reset
     32- phys: should contain a phandle to the PCIE phy
     33- phy-names: must contain "pcie"
     34
     35- device_type:
     36	should be "pci". As specified in snps,dw-pcie.yaml
     37
