Register the qoriq cpufreq driver as a cooling device, based on the thermal device tree framework. When temperature crosses the passive trip point cpufreq is used to throttle CPUs. Signed-off-by: Jia Hongtao <redacted> Reviewed-by: Viresh Kumar <viresh.kumar@linaro.org>Applied, thanks!I got a randconfig build error today: drivers/built-in.o: In function `qoriq_cpufreq_ready': debugfs.c:(.text+0x1f4688): undefined reference to `of_cpufreq_cooling_register' CONFIG_OF=y CONFIG_QORIQ_CPUFREQ=y CONFIG_THERMAL=m CONFIG_THERMAL_OF=y I think you need a 'depends on THERMAL' to prevent the driver from being built-in when THERMAL=m. ArndCorrect. I need to add following lines to the Kconfig file: depends on !CPU_THERMAL || THERMAL=y Hi Rafael, Should I send a new patch include this fix or send a fix patch?
Why THERMAL=y and not just THERMAL, which would allow building this driver as a module? -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
