Well, there are still some registers within twl6030 that could be
accessed through the control channel, it is just that the voltage
registers are no longer visible through this. We have the CFG_GRP,
CFG_TRANS, CFG_STATE and CFG_STEP registers visible here, even though we
are not accessing them right now.
