IMO it's best to continue using the "base soc" (which just so happened
to fall onto sc7280 this time around) for all compatibles, unless the
derivatives actually had changes

as far as firmware goes, I *think* CrOS doesn't even have PMIC_GLINK?
There are however WoA 7280 laptops which totally should have it.. Would
be nice to hunt some down and see if they report different stuff to
what's there on android firmware
