[PATCH 0/3] Add support for switch on Armanda 370 RD

[PATCH 0/3] Add support for switch on Armanda 370 RD

[Andrew Lunn]

This patchset adds support for the switch chip found on the Marvell
370 RD board. The first patch extends the current mv88e6171 driver to
also support the mv88e6172. The second patch described the switch in
the device tree of the board, and the last patch enables require build
options in mvebu_v7_defconfig.

Davem should take patch #1
Jason Cooper should take patch #2 and #3.

  mvebu: 370 RD: Add support for the switch
  mvebu: defconfig: Enable the mv88E6171 switch driver

[PATCH 1/3] dsa: mv88e6171: Add support for mv88e6172

[Andrew Lunn]

The mv88e6172 is very similar to the mv88e6171.  So extend the
mv88e6171 driver to support it.

Applied to net-next, thanks.

[PATCH 2/3] mvebu: 370 RD: Add support for the switch

[Andrew Lunn]

The 370 rd has a 7 port, mv88E6182 switch, connected to eth1.  Add a
fixed-link subnode to the ethernet device tree node, to force
gigabit/full duplex.  Add a dsa node, with describing the four used
ports. This requires adding an alias to the mdio node, so it can be
referenced as a phandle.

[PATCH 3/3] mvebu: defconfig: Enable the mv88E6171 switch driver

[Andrew Lunn]

This switch is used by the 370-rd. Enable it and support for
fixed-link phy configuration.
