20 +The device inherits all the properties of the dwmac/stmmac devices
21 +described in the file net/stmmac.txt with the following changes.
22 +
23 +Required properties:
24 +
25 +- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
26 +             and any applicable more detailed version number
27 +             described in net/stmmac.txt
28 +
29 +- qcom,nss-common: should contain a phandle to a syscon device mapping the
30 +                  nss-common registers.
31 +
32 +- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
33 +                  qsgmii-csr registers.

35 +Example:
36 +
37 +       gmac: ethernet@37000000 {
38 +               device_type = "network";
