Hello,
I am working on OMAP3 + TWL4030 combination for ASoC codec
The omap generic omap-pcm.c file has
static const struct snd_pcm_hardware omap_pcm_hardware = {
.info = SNDRV_PCM_INFO_MMAP |
SNDRV_PCM_INFO_MMAP_VALID |
SNDRV_PCM_INFO_INTERLEAVED |
SNDRV_PCM_INFO_BLOCK_TRANSFER |
SNDRV_PCM_INFO_PAUSE |
SNDRV_PCM_INFO_RESUME,
.formats = SNDRV_PCM_FMTBIT_S16_LE,
.rates = SNDRV_PCM_RATE_8000_96000,
.period_bytes_min = 32,
.period_bytes_max = 64 * 1024,
.periods_min = 2,
.periods_max = 255,
.buffer_bytes_max = 128 * 1024,
};
following structure,
When i play with
