#define PSC_I2S_FORMATS

Value:

(SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_BE | \
             SNDRV_PCM_FMTBIT_S24_BE | SNDRV_PCM_FMTBIT_S32_BE)

PSC_I2S_FORMATS: audio formats supported by the PSC I2S mode

Definition at line 35 of file mpc5200_psc_i2s.c.

#define PSC_I2S_RATES

Value:

(SNDRV_PCM_RATE_5512 | SNDRV_PCM_RATE_8000_192000 | \
            SNDRV_PCM_RATE_CONTINUOUS)

PSC_I2S_RATES: sample rates supported by the I2S

This driver currently only supports the PSC running in I2S slave mode, which means the codec determines the sample rate. Therefore, we tell ALSA that we support all rates and let the codec driver decide what rates are really supported.
