[PATCH v3 3/4] regulator: spacemit: MFD_SPACEMIT_P1 as dependencies
Posted by Troy Mitchell 1 week, 6 days ago
REGULATOR_SPACEMIT_P1 is a subdevice of P1 and should depend on
MFD_SPACEMIT_P1 rather than selecting it directly. Using 'select'
does not always respect the parent's dependencies, so 'depends on'
is the safer and more correct choice.

Since MFD_SPACEMIT_P1 already depends on I2C_K1, the dependency
in REGULATOR_SPACEMIT_P1 is now redundant.

Additionally, the default value depends on MFD_SPACEMIT_P1 rather
than ARCH_SPACEMIT.

If possible:

	default m if MFD_SPACEMIT_P1
