The CPU cooling driver (cpu_cooling.c) allows the platform's cpufreq driver to register as a cooling device and cool down the platform by throttling the CPU frequency. In order to be able to auto-register a cpufreq driver as a cooling device from the cpufreq core, we need access to code inside cpu_cooling.c which, in turn, accesses code inside thermal core. CPU_FREQ is a bool while THERMAL is tristate. In some configurations (e.g. allmodconfig), CONFIG_THERMAL ends up as a module while CONFIG_CPU_FREQ is compiled in. This leads to following error: drivers/cpufreq/cpufreq.o: In function `cpufreq_offline': cpufreq.c:(.text+0x407c): undefined reference to `cpufreq_cooling_unregister' drivers/cpufreq/cpufreq.o: In function `cpufreq_online': cpufreq.c:(.text+0x70c0): undefined reference to `of_cpufreq_cooling_register' Given that platforms using CPU_THERMAL usually want it compiled-in so it is available early in boot, make CPU_THERMAL depend on THERMAL being compiled-in instead of allowing it to be a module. As a result of this change, get rid of the ugly (!CPU_THERMAL || THERMAL) dependency in all cpufreq drivers using CPU_THERMAL. Suggested-by: Rafael J.
