In the bootloader code enabling the DC-DC is critical. There is a known

Why would the driver not provide these operations?

I didn't implement this operation because the suggested workaround for the
hardware issue isn't very nice 
(disable brownout detection during enabling DC-DC). I was afraid of the
implementation.

That doesn't sound too complicated?

If the devices aren't sharing code then they should be separate drivers.

Okay. 

mxs-regulator-ldo.c
mxs-regulator-dcdc.c

What do you think of?

Sure.
