7 *
8 * Notes:
9 * The WM8753 is a low power, high quality stereo codec with integrated PCM
10 * codec designed for portable digital telephony applications.
11 *
12 * Dual DAI:-
13 *
14 * This driver support 2 DAI PCM's. This makes the default PCM available for
15 * HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
16 * voice.
17 *
18 * Please note that the voice PCM can be connected directly to a Bluetooth
19 * codec or GSM modem and thus cannot be read or written to, although it is
20 * available to be configured with snd_hw_params(), etc and kcontrols in the
21 * normal alsa manner.
22 *
23 * Fast DAI switching:-
24 *
25 * The driver can now fast switch between the DAI configurations via a
26 * an alsa kcontrol. This allows the PCM to remain open.
