+description:
+ This device is a Synopsys DWC IP, integrated on NXP S32G/R SoCs.
+ The SoC series S32G2xx and S32G3xx feature one DWMAC instance,
+ the SoC S32R45 has two instances. The devices can use RGMII/RMII/MII
+ interface over Pinctrl device or the output can be routed
+ to the embedded SerDes for SGMII connectivity.
