I took those 22 patches, applied them on top of next-20150507 (which is
just what I happened to be developing on top of right now), and rebased
my patches which add DT support. You can find the result here if you want:

git://github.com/swarren/linux-tegra.git tegra_dev

However, with that code-base, the touchpad doesn't work for me. I see a
long pause and errors during boot:

> [   61.403717] atmel_mxt_ts 1-004b: Family: 130 Variant: 1 Firmware V1.0.AA Objects: 22

... and the touchpad doesn't work once X starts. With next-20140507 plus
the patches I sent to the mailing list, everything works.

I'm not sure if I'm supposed to have some configuration file now and
that's why it doesn't work, or whether some other problem has been
introduced? If I do need a config file, can you tell me what to put into it?

Thanks for any pointers.
