RFC: V4L2 API and radio devices with multiple tuners

2012-05-19 Thread Hans de Goede
Hi Hans et all, Currently the V4L2 API does not allow for radio devices with more then 1 tuner, which is a bit of a historical oversight, since many radio devices have 2 tuners/demodulators 1 for FM and one for AM. Trying to model this as 1 tuner really does not work well, as they have 2 complete
