[PATCH v3 0/5] Add multiple-consumer support to int3472-tps68470 driver

Hello all

At the moment there are a few places in the int3472-tps68470 driver that are
limited to just working with a single consuming device dependent on the PMIC.
There are systems where multiple camera sensors share a single TPS68470, so
we need to extend the driver to support them. This requires a couple of tweaks
to the ACPI functions to fetch dependent devices, which also assumes that only
a single dependent will be found.

The v2 for this series was some time ago...it's kept falling to the back of my
to-do list so I've only just gotten round to it; sorry about that. v2 here:

Thanks
Dan
