I'm not getting any interrupts in the unicam driver. BTW, when s_dv_timings is called, then you need to update the v4l2_format as well to the new width and height. I noticed that that didn't happen. Anyway, this is good enough for me for now since I want to add CEC support to the tc driver, and I do not need streaming for that... Regards, Hans
