So I wanted to test this but with both my somewhat cleaned up nwl driver=B9 and the nwl driver forward ported from the nxp vendor tree I'm looking at a black screen with current mainline - while my dcss forward port gives me nice output on mipi dsi. Do you have a tree that uses mipi dsi on imx8mq where I could look at to check for differences? Cheers, -- Guido > = > 2.
