Subject: [PATCH v4 0/9] cpufreq: Add flag to auto-register as cooling device
Date:   Mon, 28 Jan 2019 12:11:25 +0530
Message-Id: <cover.1548654899.git.amit.kucheria@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add a flag for cpufreq drivers to tell cpufreq core to auto-register
themselves as a thermal cooling device.

There series converts over all the drivers except arm_big_little.c.
Tested on SDM845 with the qcom-cpufreq-hw driver. Only compile-tested the
others.

Things needing fixing (but not a blocker for the series):
 - Look at how to detect that we're not in IKS mode in arm_big_little's
   .ready callback.

Chnages since v3:
 - Got rid of wrapper function to register/unregister cooling devices.
   Directly call the function in cpufreq.c

Changes since v2:
 - Get rid of #ifdef'ery and let the pointer exist in all cases
 - Get rid of (!CPU_THERMAL || THERMAL) dependency in all cpufreq drivers'
   Kconfig

Changes since v1:
- Fix compilation failures with allmodconfig
- Get rid of #ifdef in cpufreq.c
- Removed miscellaneous patches and sent them separately
- Merged patches 1 and 2 from v1

Amit Kucheria (9):
  thermal: cpu_cooling: Require thermal core to be compiled in
  cpufreq: Auto-register the driver as a thermal cooling device if asked
  cpufreq: qcom-hw: Register as a cpufreq cooling device
  cpufreq: imx6q: Use auto-registration of thermal cooling device
  cpufreq: cpufreq-dt: Use auto-registration of thermal cooling device
  cpufreq: mediatek: Use auto-registration of thermal cooling device
  cpufreq: qoriq: Use auto-registration of thermal cooling device
  cpufreq: scmi: Use auto-registration of thermal cooling device
  cpufreq: scpi: Use auto-registration of thermal cooling device
