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 --- Best wishes Danila <blockquote type="cite" cite="mid:ed62d5f3-a728-4d11-9b59-28496ed267db@kernel.org"> <pre wrap="" class="moz-quote-pre"> Best regards, Krzysztof </pre> </blockquote> </body> </html>
