This API is based on earlier attempts: http://www.spinics.net/lists/linux-media/msg48391.html http://www.spinics.net/lists/linux-media/msg48435.html And an irc discussion: http://linuxtv.org/irc/v4l/index.php?date=2012-06-26 This irc discussion also talked about adding rangelow/high to the v4l2_hw_freq_seek struct, but I decided not to do that. The hwseek additions are independent to this patch series, and I think it is best if Hans de Goede does that part so that that API change can be made together with a driver that actually uses it. In order to show how the new ioctl is used, this patch series adds support for it to the very, very old radio-cadet driver. Comments are welcome! Regards, Hans PS: Mauro, I haven't been able to work on the radio profile yet, so that's not included.
