Messages in this thread Patch in this message | | | From | Amit Kucheria <> | Subject | [PATCH v1 01/10] cpufreq: Add thermal_cooling_device pointer to struct cpufreq_policy | Date | Mon, 14 Jan 2019 22:04:53 +0530 |
| |
Several cpufreq drivers register themselves as thermal cooling devices. Adding a pointer to struct cpufreq_policy removes the need for them to store this pointer in a private data structure.
We can then auto-register the cpufreq driver as a thermal cooling device from cpufreq core code.
