Great. Thanks, Bake. Last question, and then this directory is done
(sorry, I probably should have put this all on one email).
http://wiki.gnewsense.org/Kernel/Ubuntu-hardy-linux-ubuntu-modules-2-6-24-16-23--ubuntu--media--cx88--cx88-tvaudio-c
has the following introduction:
Lot of voodoo here. Even the data sheet doesn't help to
understand what is going on here, the documentation for the audio
part of the cx2388x chip is *very* bad.
Some of this comes from party done linux driver sources I got from
[undocumented].
Some comes from the dscaler sources, one of the dscaler driver guy works
for Conexant ...
And it has long static structs like this:
static const struct rlist nicam_bgdki_common[] = {
{AUD_AFE_12DB_EN, 0x00000001},
{AUD_RATE_ADJ1, 0x00000010},
{AUD_RATE_ADJ2, 0x00000040},
{AUD_RATE_ADJ3, 0x00000100},
{AUD_RATE_ADJ4, 0x00000400},
{AUD_RATE_ADJ5, 0x00001000},
{AUD_ERRLOGPERIOD_R, 0x00000fff},
{AUD_ERRINTRPTTHSHLD1_R, 0x000003ff},
{AUD_ERRINTRPTTHSHLD2_R, 0x000000ff},
{AUD_ERRINTRPTTHSHLD3_R, 0x0000003f},
{AUD_POLYPH80SCALEFAC, 0x00000003},
{AUD_DEEMPHGAIN_R, 0x000023c2},
{AUD_DEEMPHNUMER1_R, 0x0002a7bc},
{AUD_DEEMPHNUMER2_R, 0x0003023e},
{AUD_DEEMPHDENOM1_R, 0x0000f3d0},
{AUD_DEEMPHDENOM2_R, 0x00000000},
{AUD_PDF_DDS_CNST_BYTE2, 0x06},
{AUD_PDF_DDS_CNST_BYTE1, 0x82},
{AUD_QAM_MODE, 0x05},
{ /* end of list */ },
};
There doesn't seem to be any other signs of firmware.
