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.
