Subject: [PATCHv3 4/9] cpufreq: imx6q: Use auto-registration of thermal cooling device
Date: Fri, 25 Jan 2019 12:32:24 +0530 [thread overview]
Message-ID: <e650f3a7a79803173cafc28716a205e87025007c.1548398851.git.amit.kucheria@linaro.org> (raw)
In-Reply-To: <cover.1548398851.git.amit.kucheria@linaro.org>
In-Reply-To: <cover.1548398851.git.amit.kucheria@linaro.org>
Use the CPUFREQ_AUTO_REGISTER_COOLING_DEV flag to allow cpufreq core to
automatically register as a thermal cooling device.
This allows removal of boiler plate code from the driver.
