* wm8753.c -- WM8753 ALSA Soc Audio driver |

* Copyright 2003-11 Wolfson Microelectronics PLC. |
|
* Author: Liam Girdwood <[email protected]> |
|
* |
|
* Notes: |
|
* The WM8753 is a low power, high quality stereo codec with integrated PCM |
|
* codec designed for portable digital telephony applications. |
|
* |
|
* Dual DAI:- |
|
* |
|
* This driver support 2 DAI PCM's. This makes the default PCM available for |
|
* HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for |
|
* voice. |
|
* |
|
* Please note that the voice PCM can be connected directly to a Bluetooth |
|
* codec or GSM modem and thus cannot be read or written to, although it is |
|
* available to be configured with snd_hw_params(), etc and kcontrols in the |
|
* normal alsa manner. |
|
* |
|
* Fast DAI switching:- |
|
* |
|
* The driver can now fast switch between the DAI configurations via a |
|
* an alsa kcontrol. This allows the PCM to remain open. |
