These two patches look good to me.

I think we need to take both patches through the Tegra tree, since if 
the Tegra DTs start referencing the new pingroup, the driver must 
already know about it or it'll error out. So, I hope for an ack from Linus.

Of course, this only applies if you're sending patches to board .dts 
files to use the new feature for 3.18; if not, we can apply the pinctrl 
driver through the pinctrl tree instead, and wait until 3.19 to use the 
new pingroup. I assume you'll want to use the new feature soon though:-)
