Gregory CLEMENT - Aug. 23, 2013, 7:32 a.m.
The mv64xxx-i2c embedded in the Armada XP have a new feature to
offload i2c transaction. This new version of the IP come also with
some errata. This lead to the introduction to a another compatible
string.

This commit updates the Device Tree binding documentation accordingly.

Changelog v6 -> v7:

- only keep "marvell,mv7230-i2c" for compatible name

- replace "For a controller which support the I2C Transaction
  Generator" by "For the Armada XP" in the examples

Ok, the new string looks sane, so I'm not opposed to that.

                                         ^ That '8' shouldn't be there.
