Thanks for the patches.

As this is a downstream driver that I never intend to upstream, I'll ignore various things like having avdd-gpio and iovcc-gpio rather than using the regulator framework to control the power rails - it just isn't worth the effort to implement it.
Similarly each commit should do a single thing, and "Update display driver" adds power control and a load of modes.

Nothing jumps out as being an issue, so I'm happy as long as all the CI checks pass.
