Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> In TPS6507x, depending on the status of DEFDCDC{2,3} pin either DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or programmed to change the output voltage. The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.
