Document the interconnects property which is a list of interconnect paths that is used by the framebuffer and therefore needs to be kept alive when the framebuffer is being used.

Anything which needs some sort of resources in unknown way is not simple anymore. You need device specific bindings.
In this context, 'simple' means that this device cannot change display modes or do graphics acceleration. The hardware itself is not necessarily simple. As Javier pointed out, it's initialized by firmware on the actual hardware. Think of 'VGA-for-ARM'. We need these resources to keep the display working. Best regards Thomas
