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= =20 > 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. --jI8keyz6grp/JLjh Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl7gryQACgkQJNaLcl1U h9DsNQf/QMOcKgKBR1OfTOXetzJw0GYmTTeWBRwrDxvOzlh/codHfgyJ97CrHmOY 1+Th0yTlUfe69S3B5iZpER3S5jU+lsZmkeaKBNfxx3qykrWDpRi3FQG5AIOEBDB6 m43i71UuvaryROGVyZQWEXiQ+H6RpJ7MV7IUBSa9bFZBVwwJ0ous7/nzsPt5iwfr 0P/ZivT1TK9t/Zkp7biFYiuIZqvtDaSlO6yyPIb60D0Xq4+9XVJ+kPYnvRj7CEb5 w3RLxK78z4QCWveNCjNrhIUtynLudM63ofRP3O6qtcYQ7wRkHjvpTbOZ4JvUMoKl bdh2nZKb7xJazHo13G3QtNgjgoq/0g== =QJTj -----END PGP SIGNATURE----- --jI8keyz6grp/JLjh--
