In may not be part of ASoC, but it's part of ALSA, and I need it.  It's not 
just in your repository.

sound/core/pcm_misc.c

/**
  * snd_pcm_rate_to_rate_bit - converts sample rate to SNDRV_PCM_RATE_xxx bit

unsigned int snd_pcm_rate_to_rate_bit(unsigned int rate)
{
	unsigned int i;

	for (i = 0; i < snd_pcm_known_rates.count; i++)
		if (snd_pcm_known_rates.list[i] == rate)
			return 1u << i;
	return SNDRV_PCM_RATE_KNOT;
}
