The modes define the ON (supplying power) operating modes supported by a regulator. I should probably add some more docs/comments here...... I assume the TWL4030's ACTIVE and STANDBY modes supply power and probably all share the same register/bits with OFF (thus making it more tightly coupled in the hardware). The other two patches are fine. Would you be able to resend the first without the OFF mode patch changes.
