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.

Series level changes in v2:

- Dropped the patch that added a terminator to the existing tps68470 board data

The v1 can be found here:

Thanks
Dan
