And here i am. I can confirm it works, video source is tvp5150 (with platform data in pdata-quirks.c) in bt656 mode. Laurent, i used the two bt656 patches from your omap3isp/bt656 tree so if you want to push it you can add a Tested-by me. There is only one problem, but it's unrelated to your DT work. It's an old problem (see for example [1] and [2]), seen by other people too and it seems it's still there. Basically if i capture with yavta while the system is idle then it just waits without getting any frame. If i add some cpu load (usually i do a "cat /dev/zero" in a ssh terminal) it starts capturing correctly. The strange thing is that i do get isp interrupts in the idle case, so i don't know why they don't "propagate" to yavta. Any hints on how to debug this?
