AC97 can be 16, 18 or 20 bit. The link always transmits 20 bits.
This codec is a 20b version.
On the mpc5200 side you can only feed the FIFOs 32b data. "For each
AC97 slot a 32 bit data word must be in the TxFIFO"
So do I make these pair up?
static struct snd_soc_dai psc_ac97_dai_template[] = {
{
.name = "%s analog",
.suspend = psc_ac97_suspend,
.resume = psc_ac97_resume,
.playback = {
.channels_min = 1,
.channels_max = 6,
.rates = SNDRV_PCM_RATE_8000_48000,
.formats = SNDRV_PCM_FMTBIT_S32_BE,
},
.capture = {
.channels_min = 1,
.channels_max = 2,
.rates = SNDRV_PCM_RATE_8000_48000,
.formats = SNDRV_PCM_FMTBIT_S32_BE,
},
.ops = &psc_ac97_analog_ops,
},
{
.name = "%s digital",
.playback = {
.channels_min = 1,
.channels_max = 2,
.rates = SNDRV_PCM_RATE_32000 | \
SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000,
.formats = SNDRV_PCM_FORMAT_IEC958_SUBFRAME_BE,
},
.ops = &psc_ac97_digital_ops,
}};
