Yes I will refactor the sensor code and framework registration code.

Good idea but as Select does not enable all dependencies recursively so we ourself needs to resolve all. "depends on " is a easy way to do it with just 1 macro. BTW current exynos driver needs both CPU_FREQ and CPU_THERMAL so your patch is fine. Thanks, Amit Daniel > > any ideas on this? > > thanks, > rui > > CPU_FREQ_TABLE depends on CPU_FREQ.

there is still something unclear to me. Amit, the next step should be remove this "depends on CPU_THERMAL" line for EXYNOS driver, right? If we do this, the exynos driver should work w/ or w/o CPU_THERMAL, but should we have something like, "hey, I like CPU_THERMAL, I work better with it set"? "Select" does not work here because it may block exynos driver when CPU_FREQ cleared. any ideas on this? thanks, rui CPU_FREQ_TABLE depends on CPU_FREQ. Selecting CPU_FREQ_TABLE without checking for dependencies gives the following compilation warnings: warning: (ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC && UX500_SOC_DB8500 && CPU_THERMAL && EXYNOS_THERMAL) selects CPU_FREQ_TABLE which has unmet direct dependencies (ARCH_HAS_CPUFREQ && CPU_FREQ) Patch-based-on: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Zhang Rui <rui.zhang@intel.com> --- drivers/thermal/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
