Kconfig is overcrowded as it is now and adding yet another option which is irrelevant for some arches (for now, as you say) simply causes confusion to people with absolutely no gain. Simply take a look at all arch//Kconfig files and look at all the "select ..." statements right at the beginning of the respective Kconfig file. Each arch which has PWM drivers would select the synthetic CONFIG_ARCH_PWM option and CONFIG_PWM would depend on it. -- Regards/Gruss, Boris.
