Because that's the only one I care about. I can try to do the same for
all the others if you wish.

Yes, the ones that closely related to certain architectures or chips.

And this is already done:

REGULATOR_AB3100:
	depends on AB3100_CORE
	default y if AB3100_CORE

(if AB3100_CORE is redundant BTW)

REGULATOR_TPS6105X:
	depends on TPS6105X
	default y if TPS6105X

ditto

And in mfd:

config TPS65010
	default y if MACH_OMAP_H2 || MACH_OMAP_H3 || MACH_OMAP_OSK

config ABX500_CORE
	default y if ARCH_U300 || ARCH_U8500

config AB3100_CORE
	default y if ARCH_U300

config AB3100_OTP
	default y if AB3100_CORE

These 3 seem to be linked, but the same logic applies; most people
should say 'y', so make it the default.
