Please find the patchset at https://lore.kernel.org/all/20260506-topic-sm8650-ayaneo-pocket-s2-sgm3804-v4-0-7495e7905693@xxxxxxxxxx/
it implements full support for the SGM3804 with voltage control on both
rails.

I guess most Ayaneo boards uses common components, I also sent patches for:
- https://lore.kernel.org/all/20260430-topic-sm8650-ayaneo-pocket-s2-sy7758-v2-0-308140640de9@xxxxxxxxxx/
