First, all interfaces are searched - * for an AudioControl class interface. If found, the config descriptor - * that belongs to the current configuration is searched and - * the HEADER descriptor is found. It contains a list of - * all AudioStreaming and MIDIStreaming devices. This list is then walked, - * and all AudioStreaming interfaces are classified into input and output - * interfaces (according to the endpoint0 direction in altsetting1) (MIDIStreaming - * is currently not supported). The input & output list is then used - * to group inputs and outputs together and issued pairwise to the - * AudioStreaming class parser. Finally, all OUTPUT_TERMINAL descriptors - * are walked and issued to the mixer construction routine. - * - * The AudioStreaming parser simply enumerates all altsettings belonging - * to the specified interface. It looks for AS_GENERAL and FORMAT_TYPE - * class specific descriptors to extract the sample format/sample rate - * data. Only sample format types PCM and PCM8 are supported right now, and - * only FORMAT_TYPE_I is handled. The isochronous data endpoint needs to - * be the first endpoint of the interface, and the optional synchronisation - * isochronous endpoint the second one. - * - * Mixer construction works as follows: The various TERMINAL and UNIT - * descriptors span a tree from the root (OUTPUT_TERMINAL) through the - * intermediate nodes (UNITs) to the leaves (INPUT_TERMINAL). We walk - * that tree in a depth first manner. FEATURE_UNITs may contribute volume, - * bass and treble sliders to the mixer, MIXER_UNITs volume sliders. - * The terminal type encoded in the INPUT_TERMINALs feeds a heuristic - * to determine "meaningful" OSS slider numbers, however we will see - * how well this works in practice. Other features are not used at the - * moment, they seem less often used. Also, it seems difficult at least - * to construct recording source switches from SELECTOR_UNITs, but - * since there are not many USB ADC's available, we leave that for later. - */ - -/*****************************************************************************/ - -#include <linux/kernel.h> -#include <linux/slab.h> -#include <linux/string.h> -#include <linux/timer.h> -#include <linux/sched.h> -#include <linux/smp_lock.h> -#include <linux/module.h> -#include <linux/sound.h> -#include <linux/soundcard.h> -#include <linux/list.h> -#include <linux/vmalloc.h> -#include <linux/init.h> -#include <linux/poll.h> -#include <linux/bitops.h> -#include <asm/uaccess.h> -#include <asm/io.h> -#include <linux/usb.h> - -#include "audio.h" - -/* - * Version Information - */ -#define DRIVER_VERSION "v1.0.0" -#define DRIVER_AUTHOR "Alan Cox <alan@lxorguk.ukuu.org.uk>, Thomas Sailer (sailer@ife.ee.ethz.ch)" -#define DRIVER_DESC "USB Audio Class driver" - -#define AUDIO_DEBUG 1 - -#define SND_DEV_DSP16 5 - -#define dprintk(x) - -/* --------------------------------------------------------------------- */ - -/* - * Linked list of all audio devices... - */ -static struct list_head audiodevs = LIST_HEAD_INIT(audiodevs);
