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.

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. [unhandled content-type:application/pgp-signature] | |
