Hi,
Please consider BSD3, or at least dual-licensing with some permissive
license (so that for example BSDs can re-use these DTs).

No underscores in node names, please change this to ref-gnd (and consequently
for all other nodes). Note that this only concerns node names and not labels.

Isn't this PMIC-internal, aka accessible on all devices using PMP8074?

Are you sure no other configurations are supported with this PMIC?
Otherwise you may accidentally burn somebody's board by setting up
regulators in a place that's not usually expected to have them..
