| * ALSA: usb-audio: Assume first control interface is for audioDaniel Mack2010-09-021-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For devices with more than one control interface, let's assume the first one contains the audio controls. Unfortunately, there is no field in any of the descriptors to tell us whether a control interface is for audio or MIDI controls, so a better check is not easy to implement. On a composite device with audio and MIDI functions, for example, the code currently overwrites chip->ctrl_intf, causing operations on the control interface to fail if they are issued after the device probe.

* | ALSA: usb: USB3 SuperSpeed sound supportPaul Zimmerman2010-08-141-8/+23
|/ | | | | | | | | | | | | | | | | | | This is V2 of the patch, after feedback from Clemens and Daniel. This patch adds SuperSpeed support to the USB drivers under sound/. It adds tests for USB_SPEED_SUPER to the appropriate places that check for the USB speed. This patch has been tested with our SS USB3 device emulating a set of Yamaha speakers and a Logitech microphone, but with the descriptors modified to add USB3 support. It has also been tested with the real speakers and microphone, to make sure that USB2 devices still work.

* ALSA: usb-audio: unify UAC macros and struct namesDaniel Mack2010-06-231-1/+1
| | | | | | | | | | Get rid of the last occurances of _v1 suffixes, and move the version number right after the "uac" string. Now things are consitent again. Sorry for the forth and back, but it just looks much nicer this way. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: usb-audio: parse clock topology of UAC2 devicesDaniel Mack2010-05-311-16/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Audio devices which comply to the UAC2 standard can export complex clock topologies in its descriptors and set up links between them. The entities that are defined are - clock sources, which define the end-leafs. - clock selectors, which act as switch to select one out of many possible clocks sources. - clock multipliers, which have an input clock source, and act as clock source again. They can be used to derive one clock from another. All sample rate changes, clock validity queries and the like must go to clock source elements, while clock selectors and multipliers can be used as terminal clock source. The following patch adds a parser for these elements and functions to iterate over the tree and find the leaf nodes (clock sources). The samplerate set functions were moved to the new clock.c file.

* linux/usb/audio.h: split headerDaniel Mack2010-03-121-1/+2
| | | | | | | | | | | | | - Split the audio.h file in two to clearly denote the differences between the standards. - Add many more defines to audio-v2.h. Most of them are not currently used. - Replaced a magic value with a proper define Signed-off-by: Daniel Mack <daniel@caiaq.de> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Cc: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: usb-audio: refactor codeDaniel Mack2010-03-051-0/+648
Clean up the usb audio driver by factoring out a lot of functions to separate files. Code for procfs, quirks, urbs, format parsers etc all got a new home now. Moved almost all special quirk handling to quirks.c and introduced new generic functions to handle them, so the exceptions do not pollute the whole driver. Renamed usbaudio.c to card.c because this is what it actually does now. Renamed usbmidi.c to midi.c for namespace clarity. Removed more things from usbaudio.h. The non-standard drivers were adopted accordingly. Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
