It's not just menuconfig: $ grep -e CONFIG_ARCH_STI -e CONFIG_CLKSRC_ST_LPC .config CONFIG_ARCH_STI=y CONFIG_CLKSRC_ST_LPC=y CONFIG_CLKSRC_ST_LPC_TIMER_SCHED_CLOCK=y $ vim .config $ grep -e CONFIG_ARCH_STI -e CONFIG_CLKSRC_ST_LPC .config CONFIG_ARCH_STI=y # CONFIG_CLKSRC_ST_LPC is not set # CONFIG_CLKSRC_ST_LPC_TIMER_SCHED_CLOCK is not set $ make ARCH=arm silentoldconfig scripts/kconfig/conf --silentoldconfig Kconfig # # configuration written to .config # $ grep -e CONFIG_ARCH_STI -e CONFIG_CLKSRC_ST_LPC .config CONFIG_ARCH_STI=y CONFIG_CLKSRC_ST_LPC=y CONFIG_CLKSRC_ST_LPC_TIMER_SCHED_CLOCK=y So I think that, if you want to be able to set CLKSRC_ST_LPC_TIMER_SCHED_CLOCK to 'n' even though CLKSRC_ST_LPC is 'y', you need to add a prompt. Or have you found a way around this?
