Re: AverMedia Satelllite Hybrid+FM A706

Update 2:
all I2C breakage is caused by i2c gates in CE6313 and TDA8290 so I just
commented-out the calls in tuner drivers for now.
Tuner detection in tda8290 breaks because it finds CE5039 at 0x60. Disabling
CE5039 using GPIO in board_init1() and enabling it in dvb_init() allows all
chips to initialize properly:

The card comes to life slowly: FM radio works for a couple of seconds!
With arecord | aplay, noise is played. When a radio station is tuned
(v4l2ctl -d /dev/radio0 -f something), I can hear it clearly for a 2-3 seconds,
then it fades to noise.

These errors appear in log:
