This message is always there, and is harmless (the regulator is 
optional).

This is indeed related to the rk3399 DT issue, and how the bisected 
patch
only makes it plain that the DT has always been broken. The patches you 
point
to should paper over the problem, and I'd appreciate some feedback on 
them.

There may be a few more systems affected by this issue (at least MTK and 
QC
systems could be affected as well).
