I guess the easiest would be to take this all into the Tegra tree. Apart
from patches 1, 12 and 14 everything would go via that anyway. I'll also
take some time this week to give the series some review, I don't think I
have looked at this code at all yet.

Mike, you "looks good to me"'d patches 1, 12 and 14, does that translate
to an Acked-by?
