====================
net: ethernet: bgmac: Add platform device support

David Miller, Please consider including patches 1-5 in net-next

Florian Fainelli, Please consider including patches 6 & 7 in
  devicetree/next

Changes in v2:
* Made device tree binding changes suggested by Sergei Shtylyov,
  Ray Jui, Rob Herring, Florian Fainelli, and Arnd Bergmann
* Removed devm_* error paths in the bgmac_platform.c suggested by
  Florian Fainelli
* Added Arnd Bergmann's Acked-by to the first 5 (there were changes
  outlined in the bullets above, but I believe them to be minor enough
  for him to not revoke his acks)

This patch series adds support for other, non-bcma iProc SoC's to the
bgmac driver.  This series only adds NSP support, but we are interested
in adding support for the Cygnus and NS2 families (with more possible
down the road).

To support non-bcma enabled SoCs, we need to add the standard device
tree "platform device" support.  Unfortunately, this driver is very
tighly coupled with the bcma bus and much unwinding is needed.  I tried
to break this up into a number of patches to make it more obvious what
was being done to add platform device support.  I was able to verify
that the bcma code still works using a 53012K board (NS SoC), and that
the platform code works using a 58625K board (NSP SoC).
