Would have been helpful to start a new thread, missed this the first time
around.

no error print here.

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.
