That should be (ARCH_OMAP || COMPILE_TEST) && MFD_SYSCON

This is exactly the same as it was the first time it was posted and is
still buggy. To repeat the get and set voltage functions should reflect
the actual voltage set in the hardware.

If the enable mask really can have multiple bits this won't do the right
thing - it'll return true if any bits are set. It needs to make sure
all the bits are set.

This doesn't match your implementation which can only set two voltages.
