Hi,

this series adds support for hardware-triggered thermal reset to the PMC
driver. Namely, it adds device tree properties for specifying the I2C
command to be sent when thermtrip is triggered. It is to be noted
that thermtrip won't be ever triggered without a soctherm driver to
calibrate the sensors, but I'll follow up with that patch.

pmc.c required some juggling around to make the match data usable in
probe, since I didn't want to put the code into the initcall either, since
the soctherm driver won't be initialized by that point anyway.

Series tested on Jetson-TK1. Should work on Tegra30 and Tegra114 too.

Can you describe the procedure used to test this? We currently have a
bunch of features in Tegra that some people have tested at some point
during development but the test procedures never got documented. That
means whenever we want to test something we need to go and reinvent a
bunch of tests after the fact.

So what I'd like to start doing is collect tests (preferably in some
scripted way) so that they can be kept in a repository that people can
easily clone and run on devices.

Could you provide something like that for thermtrip?

Sure. I'll see if I can make a just a test script or if a local patch is
needed to test. Btw, I also have a pretty nice test script for EMC
ready, and I agree that such a repository would be very nice.

Here is a test program. It it works, the device with immediately shut down.

Is there a way to set the trip temperature without going through
/dev/mem? I'd expect the device to have a sysfs interface of some
sort.
