I'd like for my application to semi-directly send a signal to my customized ADV7170 video chip driver. How do I do this? I'm thinking my application should call ioctl() with parameters I don' t yet understand, and then I code some structure values in the ADV7170 driver that I also don't yet understand. Please help me understand, or correct me and tell me how to really do it!!!
Thanks,
Helmut
