H A Doverview.rst6 provide better ALSA support for embedded system-on-chip processors (e.g.
7 pxa2xx, au1x00, iMX, etc) and portable audio codecs. Prior to the ASoC
8 subsystem there was some support in the kernel for SoC audio, however it
9 had some limitations:-
11 * Codec drivers were often tightly coupled to the underlying SoC
12 CPU. This is not ideal and leads to code duplication - for example,
15 * There was no standard method to signal user initiated audio events (e.g.
18 machine specific code to re-route audio, enable amps, etc., after such an
21 * Drivers tended to power up the entire codec when playing (or
22 recording) audio. This is fine for a PC, but tends to waste a lot of

H A Dcodec.rst2 ASoC Codec Class Driver
5 The codec class driver is generic and hardware independent code that configures
6 the codec, FM, MODEM, BT or external DSP to provide audio capture and playback.
11 Each codec class driver *must* provide the following features:-
13 1. Codec DAI and PCM configuration
14 2. Codec control IO - using RegMap API
15 3. Mixers and audio controls
16 4. Codec audio operations
