| 13 | * Notes: |
| 14 | * The WM8753 is a low power, high quality stereo codec with integrated PCM |
| 15 | * codec designed for portable digital telephony applications. |
| 16 | * |
| 17 | * Dual DAI:- |
| 18 | * |
| 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 |
| 21 | * voice. |
| 22 | * |
| 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 |
| 26 | * normal alsa manner. |
| 27 | * |
| 28 | * Fast DAI switching:- |
| 29 | * |
| 30 | * The driver can now fast switch between the DAI configurations via a |
| 31 | * an alsa kcontrol. This allows the PCM to remain open. |
