thermal/drivers/clock_cooling: Remove clock_cooling code

2020-07-21T08:40:08Z

clock_cooling has no in-kernel users. It has never found any use in drivers as far as I can tell. Remove the code. Signed-off-by: Amit Kucheria Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/aa5d5ac2589cf7b14ece882130731b4a916849a6.1593619943.git.amit.kucheria@linaro.org

thermal/drivers/clock_cooling: Include export.h

2020-05-22T16:48:54Z

It is preferrable to include export.h when you are using EXPORT_SYMBOL family of macros. Signed-off-by: Amit Kucheria Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/25f16415ab7b7587a052f1bce4133da318d58192.1589199124.git.amit.kucheria@linaro.org

thermal/drivers/clock_cooling: Sort headers alphabetically

2020-05-22T16:48:53Z

Sort headers to make it easier to read and find duplicate headers. Signed-off-by: Amit Kucheria Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/f8e1258fd8b882bab018de63c7e713b4334fec30.1589199124.git.amit.kucheria@linaro.org

thermal/drivers/cpu_cooling: Rename to cpufreq_cooling

2020-01-27T09:24:32Z

As we introduced the idle injection cooling device called cpuidle_cooling, let's be consistent and rename the cpu_cooling to cpufreq_cooling as this one mitigates with OPPs changes.

thermal: convert clock cooling to use an IDA

2017-01-04T04:47:28Z

thermal clock cooling does not use the ability to look up pointers by ID, so convert it from using an IDR to the more space-efficient IDA. Signed-off-by: Matthew Wilcox Signed-off-by: Zhang Rui

thermal: clock_cooling: Fix missing mutex_init()

2016-08-08T02:57:39Z

The driver allocates the mutex but not initialize it. Use mutex_init() on it to initialize it correctly. This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun Signed-off-by: Zhang Rui

thermal: introduce clock cooling device

2014-11-20T14:43:16Z

This patch introduces a new thermal cooling device based on common clock framework. The original motivation to write this cooling device is to be able to cool down thermal zones using clocks that feed co-processors, such as GPUs, DSPs, Image Processing Co-processors, etc. But it is written in a way that it can be used on top of any clock. The implementation is pretty straight forward. The code creates a thermal cooling device based on a pair of a struct device and a clock name. The struct device is assumed to be usable by the OPP layer. The OPP layer is used as source of the list of possible frequencies. The (cpufreq) frequency table is then used as a map from frequencies to cooling states. Cooling states are indexes to the frequency table. The logic sits on top of common clock framework, specifically on clock pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is only allowed when the new rate is within the thermal limit (cooling state -> freq). When a thermal cooling device state transition is requested, the clock is also checked to verify if the current clock rate is within the new thermal limit.
