ARM_BIG_LITTLE_CPUFREQ is the core cpufreq code for big LITTLE SoC's and every other driver will be a glue providing ops to it. So, ARM_DT_BL_CPUFREQ does depend on ARM_BIG_LITTLE_CPUFREQ and that's why i added depends on ARM_CPU_TOPOLOGY in ARM_BIG_LITTLE_CPUFREQ only and depends on ARM_BIG_LITTLE_CPUFREQ in ARM_DT_BL_CPUFREQ. But the problem is if ARM_DT_BL_CPUFREQ isn't selected then we still get ARM_DT_BL_CPUFREQ enabled in menuconfig but a warning just before compilation. Which Arnd pointed to..
