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. | |
