[PATCH 0/3] support GMAC for RK3399 & RK3366

[Roger Chen]

This series adds registers description for RK3366 & RK3399 GMAC.
And also DT nodes for RK3399 SoC and EVB.

[PATCH 1/3] net: stmmac: dwmac-rk: add rk3366 & rk3399 specific data

[Roger Chen]

Add constants and callback functions for the dwmac on rk3228/rk3229 socs.
As can be seen, the base structure is the same, only registers and the
bits in them moved slightly.
