Subject: Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2af78448fff6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Merge branch 'release' of git://git./linux/kernel/git/rzhang/linux

Pull thermal management updates from Zhang Rui:
 "Highlights:

   - introduction of Dove thermal sensor driver.

   - introduction of Kirkwood thermal sensor driver.

   - introduction of intel_powerclamp thermal cooling device driver.

   - add interrupt and DT support for rcar thermal driver.

   - add thermal emulation support which allows platform thermal driver
     to do software/hardware emulation for thermal issues."

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (36 commits)
  thermal: rcar: remove __devinitconst
  thermal: return an error on failure to register thermal class
  Thermal: rename thermal governor Kconfig option to avoid generic naming
  thermal: exynos: Use the new thermal trend type for quick cooling action.
  Thermal: exynos: Add support for temperature falling interrupt.
  Thermal: Dove: Add Themal sensor support for Dove.
  thermal: Add support for the thermal sensor on Kirkwood SoCs
  thermal: rcar: add Device Tree support
  thermal: rcar: remove machine_power_off() from rcar_thermal_notify()
  thermal: rcar: add interrupt support
  thermal: rcar: add read/write functions for common/priv data
  thermal: rcar: multi channel support
  thermal: rcar: use mutex lock instead of spin lock
  thermal: rcar: enable CPCTL to use hardware TSC deciding
  thermal: rcar: use parenthesis on macro
  Thermal: fix a build warning when CONFIG_THERMAL_EMULATION cleared
  Thermal: fix a wrong comment
  thermal: sysfs: Add a new sysfs node emul_temp for thermal emulation
  PM: intel_powerclamp: off by one in start_power_clamp()
  thermal: exynos: Miscellaneous fixes to support falling threshold interrupt
