Hi Hartmut,
I was wrong:
->There is no difference if I use this:
-> saa7134_set_gpio(dev, 22, 1);
->or this:
-> saa7134_set_gpio(dev, 21, 1);
This is wrong.
It only works at all when it is this: saa7134_set_gpio(dev, 22, 1);
With this: saa7134_set_gpio(dev, 21, 1); it does not scan anything at all.
I proved this out by modifying the source, rebuild v4l-dvb,
and then instead of rebooting, I power-cycled each time.
There are 2 problems here:
1) With no modification, I must switch to analog tv before I can switch
to dvb-t.
If I am using Kaffeine, and then wish to use Me-tv, I must view
analog tv
in between.
2) With no modification, dvb-t will not scan SBS unless analog tv viewed
first.
With this modification, both problems vanish.
I have not yet tested radio.
Regards,
Tim
