It depends on the panel-bridge layer I've submitted. The RPi DSI stack isn't completely working yet -- I've got some flickery pixels on the display where it seems some color values are unstable (on the default debian swirl desktop image, they're particularly visible as pink sparkles near the edge of the swirls). So far messing with clocks, not setting clocks at all, forcing the firmware's DSI timings, and a bunch of other hacks haven't managed to resolve it. Still, I think this driver stack is useful to have, and I assume that fixing this will be a small bugfix somewhere later.
