Adds I2C bus driver for nVidia Tegra SoCs. Tegra includes 4 I2C controllers, one of which is inside the Dynamic Voltage Controller and has a slightly different register map. Signed-off-by: Colin Cross <redacted>
Would have been helpful to start a new thread, missed this the first time around.

you might want to think about having a seperate platform bus name for this case, and switching the is_dvc field on that. It'll make life much easier if someone decides that what the next tegra i2c needs is 5 i2c controllers. I'll consider putting this (as is) into the -next tree, but would like to see the issues with readsl/writesl sorted out and any other review comments sorted. -- Ben Dooks, ben at fluff.org, http://www.fluff.org/ben/ Large Hadron Colada: A large Pina Colada that makes the universe disappear.
