2021-03-25drm/bridge: lt9611: Fix handling of 4k panelsRobert Foss
4k requires two dsi pipes, so don't report MODE_OK when only a single pipe is configured. But rather report MODE_PANEL to signal that requirements of the panel are not being met.

DSI end-points are supposed to be at node 0 and node 1 as per binding. So fix this and use node 0 and node 1 for dsi.
