Yuan MPC788 and MPC583

["Paul" <Paul@xxxxxxxxxxxxxxx>]

Hi All,

I now have both these cards working up to a point, see attached patch.
There are still a few problems though.

1 - MODULE LOADING ORDER
Unless tuner.ko is loaded first, the drivers will not work.
dmesg says "xc2028 4-0061: xc2028/3028 firmware name not set!".
I guess this is because of the cx88_call_i2c_clients in cx88_card_setup.
Is there anyway around this?
Can I make cx8800.ko dependant on tuner.ko?

2 - ATSC IS UNRELIABLE
After the modules have been loaded, testing an ATSC stream with mplayer
works first time.
Subsequent testing with mplayer sometimes works and sometimes fails.
This doesn't happen with the DVB card (mplayer works every time).
azap always works, but the time until it shows 'status 1f' varies
considerable.
Any ideas what could be causing this?

3 - ANALOGUE TV AFTER DIGITAL TV
After testing ATSC or DVB with mplayer, analogue TV (using xawtv) stops
working.
Once this happens, the only way to fix it is to reboot the computer.
Removing then reinstalling the modules does not help.
This fault is common to both cards.
Any thoughts on what is going wrong?

The patch is for todays repository (v4l-dvb-b0815101889d.tar.bz2).
I doubt this patch will be any use to the main tree because of the
change to zl10353.c.
I also had to comment a bit of tuner-xc2028.c as it was causing a
segfault.


Thanks
Paul Riisenberg
