[PATCH v2 0/7] stmmac: dwmac-meson8b: configurable RGMII TX delay

2016-11-25 Thread Martin Blumenstingl
Currently the dwmac-meson8b stmmac glue driver uses a hardcoded 1/4 cycle TX clock delay. This seems to work fine for many boards (for example Odroid-C2 or Amlogic's reference boards) but there are some others where TX traffic is simply broken. There are probably multiple reasons why it's working o
