I am planning to develop IP settop box-like product which is also able to receive signal from TV tuner. ADAV4622 looks like the right part because it has SIF interface. However there is an issue about ADAV4622. The ADAV4622 must be controlled by linux-running host. That means I need linux device driver for ADAV4622. I wonder if ADI has linux driver for ADAV4622 or ADAV4622 has ever been interfaced to linux-running host up to now.
