Kernel-4.18.0-80.el8_ipq806x-dwmac

• IPQ806x DWMAC Ethernet controller

The device inherits all the properties of the dwmac/stmmac devices
described in the file net/stmmac.txt with the following changes.

Required properties:

• compatible: should be “qcom,ipq806x-gmac” along with “snps,dwmac”

      and any applicable more detailed version number
      described in net/stmmac.txt
  

• qcom,nss-common: should contain a phandle to a syscon device mapping the

       nss-common registers.
  

• qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the

       qsgmii-csr registers.
  

Example:

gmac: ethernet@37000000 {
    device_type = "network";
    compatible = "qcom,ipq806x-gmac";
    reg = <0x37000000 0x200000>;
    interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
    interrupt-names = "macirq";

    qcom,nss-common = <&nss_common>;
    qcom,qsgmii-csr = <&qsgmii_csr>;

    clocks = <&gcc GMAC_CORE1_CLK>;
    clock-names = "stmmaceth";

    resets = <&gcc GMAC_CORE1_RESET>;
    reset-names = "stmmaceth";
};
