BTW, the av7110 firmware also offers an ADSwitch command, which sets
GPIO3 (of the av7110) to high (DVB) or low (analog TV). At least
that's what the comments in the firmware source say, though I've
not been able to see any difference. The driver uses this command
anyway when switching between DVB and analog TV.
