cx88 radio working, a question though

[Malcolm V <farkit (at) iinet.net.au>]

OK, not a userspace question ;) .

I've got the radio working now on my DTV2000, to a certain extent (no auto 
tuning, but setting frequency works fine). The sound is piped via I2S to the 
cx23881. This is enabled via bit 15 of AUD_CTL. I notice that the blackbird 
code modifies this bit in places, but It's not really appropriate for my 
card.

  By adding a bit to the cx88_input structure card definition (unsigned int 
i2s_input:1; ) it should be possible for me to switch these where required 
with a simple:
if (!foo.blackbird && foo.i2s_input) /*or something to that effect */

  As nothing but blackbird fiddles with this bit at present, making this 
change shouldn't affect any existing cards* , and may allow some to enable 
radio,etc too.

  My card has a stereo audio input jack which also uses I2S input, so I need 
this for radio, svideo in and composite in.

  Should I sumbit this as two patches, one for the card without 
radio/svideo/composite support, and one with the modifications required to 
get them working?

*honest ... *blink* ... As far as I can see its never set (except in the 
blackbird case), but assumed to always be 0. The change in code will mean if 
i2s_input isn't set (the default is not set for every input), it will be 
forced to 0. If there is a card in use which always has this bit set, the 
code change will break it.

Cheers,
Malcolm V.
