I attached prototype patches (based on -rc2) for panel dpi using that
approach. It's a bit messier than I'd like, because for non-DT boot we
need to request the gpio using the old API, and then convert it to
gpio_desc. We can remove that code when all the boards use DT.

Just FYI, you can use the gpiod API with non-DT platforms if you register GPIO 
lookup entries in board code with gpiod_add_lookup_table().

Right, but as the board files are going away, I'd rather not touch them
at all if possible.
