Hello Krzysztof,

I was somewhat intrigued by your observation, especially since I have
some schematics for this device. The patch correctly adds four
regulators – ibb, lab, vdd (3p0), and vio (1p8).

This situation arises from Xiaomi’s tendency to use different panels in
various revisions of the same device. Although, AFAIK, the
sm7150-xiaomi-toco/tucana was released with only one possible variation
(which this series adds), the sm7150-xiaomi-davinci offers a different
perspective. The latter was initially produced with a samsung,ams639rq08
panel (which I had added previously), yet official service centers have
replaced the factory panel with the visionox,g1639fp106 during repairs.
This suggests that, in terms of power configuration, the
samsung,ams639rq08 and the visionox,g1639fp106 panels are effectively
identical.

It is therefore likely that the visionox,g2647fb105 from this series
follows the same way.

Nevertheless, it is reassuring that I can confirm these findings with
the schematics rather than relying on mere guesswork xD
