[PATCH 0/2] regulator: Add support for parallel regulators

On some boards, devices consuming a lot of power cannot use a single
regulator, but few of them in parallel to spread the consumption.

In such a case, we must ensure that all these regulators are kept in

Since this is something that is totally board specific, it should
obviously not be handle by each and every customer drivers that might
be driving a device wired this way on a particular board.

Instead, we implemented a regulator driver that just aggregates
several parent regulators and just forwards the regulators calls to

Let me know what you think,
