That's really what I want and it seems like it would make a lot of dts files more simple. Because, if you have an external regulator feeding the mmc with power you should set it up and use it. Now, we do have cases where it's actually the MMC controller that manges the power to the card. So no external regulators being used. For these case we have the "voltage-ranges" DT binding, but I don't think you should be using that for these cases. :-) Kind regards Uffe
