Subject: [RFC 0/3] pinctrl: add a driver for NVIDIA Tegra

This isn't quite ready for merging yet; there are some issues that need
to be sorted out w.r.t. how to replace the existing Tegra pinmux driver
first. However, I figured it'd be good to get a review of the pinctrl
driver itself now that it should be complete.

The first patch is the driver. The other 2 patches are hacks that I use
to test it, just in case anyone is interested. Patch 2 would be fixed
before actually submitting, and patch 3 dropped.
