so multiple updates:
- i think iommu works now! afaik this is mem management for the gpu and a neccessary prereq. try to get adreno 225 working but proving to be a lot harder. luckily (or unluckily) iommu is broken for apq8064 so i can test if my patch works
- got the prox/light sensor working. prox is giving bogus values but light works
- linux-next with just llvm might be an issue? apparently the change i made was using both llvm and gcc, so thats why it was working https://gitlab.postmarketos.org/postmarketOS/pmaports/-/merge_requests/7335/diffs
