The "critical" type trip in thermal zone can be
set to SOC_THERM hardware, it can trigger shut down
or reset event from hardware.

I did not see in your patch set an update on the compatible string for
the new chip. Did I miss something?

As I said in the previous [00/12], the "commit 193c9d23a0f0" already added the
compatible string. At that time, it just used current tegra_soctherm.c driver to
support Tegra210, it can work, but can't show temperatures correctly.

Oh, sorry, I made a mistake, this "commit 193c9d23a0f0" just added the
compatible string, did not use current tegra_soctherm driver to support Tegra210.

Ok. got it. The binding is done, but the driver is being re factored only
now to add the support for this chip version.
