[PATCHv3 0/6] ARM: sunxi: Add support for A10 Ethernet controller

Hi,

The Allwinner A10 SoC has an ethernet controller that seem to be specific to
Allwinner. This IP has no public documentation, so exact
details are quite sparse, and this code come from refactored Allwinner
code.

Since we don't have any clock support yet for the Allwinner SoCs, we
rely on the bootloader to enable and gate the EMAC clock.

The rework to use NAPI is taking more time than expected, I'm still working
on it, but it could probably be sent as a follow-up patch.

Thanks,
Maxime

Changes from v2:
  - Split the MDIO controller to a separate driver and make use of standards
    device tree bindings
  - Fixed various minor things as suggested by Florian Fainelli

Changes from v1:
  - Use phylib for the phy-related functions
  - Use an optional regulator to power up the phy
  - Rename the driver from Davicom Wemac to Allwinner EMAC, since it's the name
    mentionned in the datasheet, and we have no strong evidence of a
    relationship with Davicom
  - Fix various small things around the driver: add defines for undocumented
    values, fix documentation name and compatible example, etc.
