Thanks.
I misunderstood the Kconfig documentation which says, "Reverse dependencies can only be used with boolean or tristate symbols". In the note following this statement doc says, "In general use select only for non-visible symbols".

The CONFIG_SPMI option is visible in menuconfig hence either it should be set by default in multi_v7_defconfig(like in qcom_defconfig) or driver owner should mention a 'depneds on CONFIG_SPMI' as suggested by Lars-Peter Clausen. 
I prefer the former (defconfig).

Shall I send a new patch adding it in multi_v7_defconfig?
