I am working on git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git

For master branch.

Is there any updated git repo that I should rebase my patch?

Would separate in the next patch.

It's a generic patch, just want to support thermal zone using a simple device tree.
Any SoC with SCSI interface and attached hard drives can benefit this change.

Normally a THERMAL_OF require a platform device to add a thermal zone.

Original drivetemp.c works quite well as a hwmon device, but no thermal zone support.

My patch just extend its capability to support a simple thermal zone created with this hwmon.

This is bind to any specific vendor, just to provide an easy way to handle cooling when hard drives' temperature gets high.
