By a 'common regulator property' I meant documented with regulator binding like *-supply, not common to MMC. How is MMC special? Thinking about this some more, what's wrong with the max current in the regulator nodes? I suppose you could have more than one load and need to define the loads separately? Rob

How is MMC special? TBH I'm surprised that these aren't defined by the MMC spec or by the ID information from the part we find connected - I'd not expect the board to be defining these at all. > Thinking about this some more, what's wrong with the max current in the > regulator nodes?

One of the bigger reasons to think about the loads would be to dynamically configure the mode the regulator is in to go into a more efficient mode when some of the devices attached to it are turned off.
