Hi,
this series adds support for the thermal monitoring features of the
soctherm unit on the Tegra124 SoC.
The branch is also available in my github repo,
git://github.com/cyndis/linux.git soctherm-v6
Thanks,
Mikko

One thing that I've wanted to start doing for a while now is request
patch submissions like this to come accompanied with a way on how to
test them. Ideally this would be in a scripted way that can test for
success programatically, but it doesn't necessarily have to be if it
turns out too difficult or impractical to do.
Indeed, that would be very useful.
The goal is to eventually come up with a test suite that can run the
majority of test cases automatically to make it easy to test for any
regressions. And even if tests can't be run automatically it'd still
be an advantage to have them all collected in some repository, since
it saves a lot of typing and time to run tests, and it will give us
a standard set of tests that everybody can verify changes against.
I realize that it's somewhat unfair to start requesting this from you
now, but we've got to start somewhere. Could you give a short summary
of how you test this? What are the interfaces that the kernel exposes
for these thermal drivers?
You need to enable the driver in Device Drivers -> Generic Thermal sysfs
driver -> Tegra SOCTHERM thermal management. Then, you should see
directories appear in /sys/class/thermal. You can also use the `tmon'
tool included in the kernel tree to quickly see values; that's what I
use for testing.
