By default, dw_mmc outputs high level voltage to indicate powering up the card and outputs low level vcltage to indicate powering off the card. But that is not always correct. The power io should be able to control different kind of hw components to supply or cutoff power to the card. We have boards that need this patchset to make the power control correct. Meanwhile let's expose it to DT for board-specific usage.
