Hi Emiliano, Hi Linus,

could you please test the patch from this series on your Odroid-C1?
I tested it on mine and Ethernet seems to be improve Ethernet transmit
speeds greatly (at the cost of a small drop in receive performance).


Changes since v2 at [1]:
- Thanks to Jianxin for providing the documentation for the two missing
  bits in pin mux register 7
- added a patch to add the missing eth_rxd2 and eth_rxd3 pin groups to
  the pinctrl-meson8b driver
- update the meson8.dtsi patch to include the eth_rxd2 and eth_rxd3 pin
  groups on top of the previous change which only removed eth_txd0_1
  and eth_txd1_1 (including the patch description)
- update subject of the cover-letter and the meson8b.dtsi patch


Changes since v1 at [0]:
- rebased so it applies on top of "ARM: dts: meson: meson8b: add the CPU
  OPP tables" which will be part of v4.20-rc1 once the arm-soc tree is
  merged into mainline
- updated patch description with more details
