1* IPQ806x DWMAC Ethernet controller
2
3The device inherits all the properties of the dwmac/stmmac devices
4described in the file net/stmmac.txt with the following changes.
5
6Required properties:
7
8- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
9 and any applicable more detailed version number
10 described in net/stmmac.txt
11
12- qcom,nss-common: should contain a phandle to a syscon device mapping the
13 nss-common registers.
14
15- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
16 qsgmii-csr registers.
