[PATCH v4 1/6] net: stmmac: dwmac-rk: add rk3366 & rk3399 specific data
From: Caesar Wang
Date: Thu Sep 01 2016 - 17:46:28 EST
From: Roger Chen <roger.chen@xxxxxxxxxxxxxx>
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.
