Overkill perhaps, but a pass through buffer chip? .. so that you can have a GPIO to enable/disable the buffer, and otherwise have some GPIOs bitbang (or another video channel?) through to the panel?
Well, the panel needs clock and data in MIPI signal levels to send commands. This is not compatible to GPIOs and GPIOs are too slow (10 MHz clock).
And, we can’t fiddle additional signals through the display cable.
So the ideal solution would just use the existing ones.
