    Yes, so it doesn't look like this is an issue.

    This:

    > sdi@80126000 {
    > vmmc-supply = <&ab8500_ldo_aux3_reg>;
    > };

    Is the same as, and will cause no more issues than:

    > static struct regulator_consumer_supply ab8500_vaux3_consumers[] = {
    > REGULATOR_SUPPLY("vmmc", "sdi0"),
    > };

    ... because only nodes which we care about (dictated by compatible
    declaration protections) will be parsed. So different platforms will not
    affect each other.

    Kind regards,
    Lee
