[PATCH 0/6] Add multiple-consumer support to int3472-tps68470 driver

[Daniel Scally <djrscally@gmail.com>]

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.

Hans - this (plus a series to media [1]) adds support for the Surface Go 2's
IR camera...the regulator settings for the Go1/2/3 world facing camera are the
same, so I'd expect them to match for the IR sensor too, which means it should
enable support for your Go too.

Thanks
Dan
