Kernel-4.18.0-80.el8_tango-pcie

Sigma Designs Tango PCIe controller

Required properties:

• compatible: “sigma,smp8759-pcie”
• reg: address/size of PCI configuration space, address/size of register area
• bus-range: defined by size of PCI configuration space
• device_type: “pci”
• #size-cells: <2>
• #address-cells: <3>
• msi-controller
• ranges: translation from system to bus addresses
• interrupts: spec for misc interrupts, spec for MSI

Example:

pcie@2e000 {
    compatible = "sigma,smp8759-pcie";
    reg = <0x50000000 0x400000>, <0x2e000 0x100>;
    bus-range = <0 3>;
    device_type = "pci";
    #size-cells = <2>;
    #address-cells = <3>;
    msi-controller;
    ranges = <0x02000000 0x0 0x00400000  0x50400000  0x0 0x3c00000>;
    interrupts =
        <54 IRQ_TYPE_LEVEL_HIGH>, /* misc interrupts */
        <55 IRQ_TYPE_LEVEL_HIGH>; /* MSI */
};
