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. 31 * 32 */ 33 34 #include <linux/module.h> 35 #include <linux/moduleparam.h> 36 #include <linux/kernel.h> 37 #include <linux/init.h> 38 #include <linux/delay.h> 39
