It's more that Cisco didn't need this since we never change the pixelport configuration after initialization. So this code should be improved. BTW, I plan to update my http://git.linuxtv.org/hverkuil/cisco.git repository today or tomorrow with our latest code that is much closer to being ready for upstreaming. > But a bridge driver working with variable sensors > and decoders can't accept this. Of course. Patches are welcome :-) > About v4l2_dv_timings, do I need to set a default timing similar to > pick PAL as default standard? Yes. Ensuring that you always have some default timing makes life a lot easier all around, both in kernelspace and in userspace. Otherwise you would have to check whether you actually have a timings setup all the time.
