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