[PATCH v3 0/4] net: expand gianfar support to ls1021a

[Renaud Barbier]

This patch adds limited support for the Ethernet controller on the NXP
LS1021A:
    * Only one port has been tested i.e enet1.
    * The PHY negotiation has been limited to 100Mbits-FD.

In this version 3, remove code that was meant to make the difference
between the mdio register offset between PPC and ARM if retrieved from
the device tree. However, the PPC platform does not support DTBs and the
mdio offset is already taken into account into the mdio access functions.
Hence, the clean up.

  gianfar: apply checkpatch recommendations
  net:gianfar: add device tree support
  ARM: ls1021a: initial Ethernet and mdio configuration
