If it is not really a property of a particular board, but something
that you would need for other boards as well, it could perhaps
be tied to the syscon functionality, or to ab3100:

ab3100_regulators_probe() could itself set up the the supply
and then set the syscon bit. Basically you just move all of
arch/arm/mach-u300/regulator.c into drivers/regulator/ab3100.c

I think this is more likely the case.

Mark: would you be OK with the ab3100 driver hogging one of its
own regulators?
