Ouch, that's not a bisect breakage, that's an *ABI breakage*. And AFAICT
this is still not okay in 2026,
see Documentation/devicetree/bindings/ABI.rst
So the bindings would need to be changed to accept both the new and old way.
Driver-wise, at a cursory look from someone not familiar with the
regulator stuff, maybe we can make it compatible with old DTS by adding
the new names as aliases ({devm_,}regulator_register_supply_alias?) as
"vin" or "buck5", if we see the old vin-supply definitions?
