  12 * Notes:
  13 *  The WM8753 is a low power, high quality stereo codec with integrated PCM
  14 *  codec designed for portable digital telephony applications.
  15 *
  16 * Dual DAI:-
  17 *
  18 * This driver support 2 DAI PCM's. This makes the default PCM available for
  19 * HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
  20 * voice.
  21 *
  22 * Please note that the voice PCM can be connected directly to a Bluetooth
  23 * codec or GSM modem and thus cannot be read or written to, although it is
  24 * available to be configured with snd_hw_params(), etc and kcontrols in the
  25 * normal alsa manner.
  26 *
  27 * Fast DAI switching:-
  28 *
  29 * The driver can now fast switch between the DAI configurations via a
  30 * an alsa kcontrol. This allows the PCM to remain open.
