Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal

Pull thermal management updates from Eduardo Valentin:

 - rework tsens driver to add support for tsens-v2 (Amit Kucheria)

 - rework armada thermal driver to use syscon and multichannel support
   (Miquel Raynal)
