Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
- Convert thermal documents to ReST (Mauro Carvalho Chehab)
- Fix a cyclic depedency in between thermal core and governors (Daniel
Lezcano)
- Fix processor_thermal_device driver to re-evaluate power limits after
resume (Srinivas Pandruvada, Zhang Rui)
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
drivers: thermal: processor_thermal_device: Fix build warning
docs: thermal: convert to ReST
thermal/drivers/core: Use governor table to initialize
thermal/drivers/core: Add init section table for self-encapsulation
drivers: thermal: processor_thermal: Read PPCC on resume
