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

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 on some boards
while it's broken on others:
- some of Amlogic's reference boards are using a Micrel PHY
- hardware circuit design
- maybe more...

The ARM arch file changes do not apply cleanly to net-next, you probably
want to merge them via the ARM tree instead of mine, and respin this series
to be without the .dts file changes.
