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

This:

> 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[] = {

... 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
