This looks fine to me, so:

Acked-by: Stephen Warren <swarren at wwwdotorg.org>

One small issue to fix though: In pinctrl-tegra.c, you've removed all
the range-checkes from the ops functions, except you forgot to update
tegra_pinctrl_disable().

This is simple enough I don't think I need to test it; it doesn't
actually apply to my local tree since it conflicts with all the pinctrl
DT work I have.
