So I should do this:
SNDRV_PCM_RATES_5512 | SNDRV_PCM_RATE_8000_192000 | SNDRV_PCM_RATE_CONTINUOUS
That's not really elegant.

In the codec driver, I do that. With ASOC, each driver specifies its own capabilities,
and ASOC is supposed to reconcile them. My I2S driver is not aware of the codec's
capabilities.
