Kernel-4.18.0-80.el8_pci-armada8k

• Marvell Armada 7K/8K PCIe interface

This PCIe host controller is based on the Synopsys DesignWare PCIe IP
and thus inherits all the common properties defined in designware-pcie.txt.

Required properties:

• compatible: “marvell,armada8k-pcie”
• reg: must contain two register regions
  • the control register region
  • the config space region
• reg-names:
  • “ctrl” for the control register region
  • “config” for the config space region
• interrupts: Interrupt specifier for the PCIe controler
• clocks: reference to the PCIe controller clocks
• clock-names: mandatory if there is a second clock, in this case the
  name must be “core” for the first clock and “reg” for the second
  one

Example:

pcie@f2600000 {
    compatible = "marvell,armada8k-pcie", "snps,dw-pcie";
    reg = <0 0xf2600000 0 0x10000>, <0 0xf6f00000 0 0x80000>;
    reg-names = "ctrl", "config";
    #address-cells = <3>;
    #size-cells = <2>;
    #interrupt-cells = <1>;
    device_type = "pci";
    dma-coherent;

    bus-range = <0 0xff>;
    ranges = <0x81000000 0 0xf9000000 0  0xf9000000 0 0x10000    /* downstream I/O */
          0x82000000 0 0xf6000000 0  0xf6000000 0 0xf00000>;    /* non-prefetchable memory */
    interrupt-map-mask = <0 0 0 0>;
