13 * The WM8753 is a low power, high quality stereo codec with integrated PCM
14 * codec designed for portable digital telephony applications.
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
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
27 * Fast DAI switching:-
29 * The driver can now fast switch between the DAI configurations via a
30 * an alsa kcontrol. This allows the PCM to remain open.
