[PATCH 00/10] thermal: tegra: Do not register cooling device

Hi,

this set of patches removes the registration of the SOCTHERM internal
throttling mechanism as cooling device. Since this throttling starts
automatically once a certain temperature threshold is crossed, it
doesn't make sense to represent it as a cooling device, which are
typically "manually" activated by the thermal framework when thermal
sensors report temperature thresholds being crossed.

Instead of using the cooling device mechanism, this statically programs
the throttling mechanism when it is configured in device tree. In order
to do this, an additional device tree property is needed to replace the
information that was previously contained in trip points.

There's a few preparatory patches to make the removal a bit simpler and
also some follow up cleanups included as well.
