I'm back to working on an ASOC driver for the STAC9766 used in the
MPC5200 based Efika.
I'm having trouble with SPDIF. I can make two devices like this in the
codec file. But how do I get the SPDIF device hooked up to the right
AC97 slot, 10/11? Are any of the ASOC codecs implementing SPDIF?
I also see that the STAC9766 is missing an ac97_patch. From my reading
of the datasheet it needs somethings fixed up.
Does the ac97 support belong in the PCI directory? It took me a while
to locate it while working on ASOC. With a model more like ASOC
codecs, the AC97 patches could be pushed into the codec files.
static struct snd_soc_dai stac9766_dai[] = {
{
.name = "STAC9766-Analog",
.id = 0,
/* stream cababilities */
.playback = {
.stream_name = "STAC9766 Analog",
.channels_min = 1,
.channels_max = 6,
.rates = STAC9766_RATES,
.formats = SNDRV_PCM_FMTBIT_S16,
},
.capture = {
.stream_name = "STAC9766 Analog",
.channels_min = 1,
.channels_max = 2,
.rates = STAC9766_RATES,
.formats = SNDRV_PCM_FMTBIT_S16,
},
/* alsa ops */
.prepare = ac97_analog_prepare,
},
{
.name = "stac9766-S/PDIF",
.id = 1,
/* stream cababilities */
.playback = {
.stream_name = "STAC9766 Digital",
.channels_min = 1,
.channels_max = 2,
.rates = STAC9766_RATES,
.formats = SNDRV_PCM_FMTBIT_S16,
},
/* alsa ops */
.prepare = ac97_digital_prepare,
}};
