ALSA: usb-audio: fix uac control query argument

2018-03-23T09:25:03+00:00

This patch fixes code readability and should have no functional change. Correct uac control query functions to account for the 1-based indexing of USB Audio Class control identifiers. The function parameter, u8 control, should be the constant defined in audio-v2.h to identify the control to be checked for readability or writeability. This patch fixes all callers that had adjusted, and makes explicit the mapping between audio_feature_info[] array index and the associated control identifier.

ALSA: usb: initial USB Audio Device Class 3.0 support

2018-03-21T10:46:33+00:00

Recently released USB Audio Class 3.0 specification introduces many significant changes comparing to previous versions, like - new Power Domains, support for LPM/L1 - new Cluster descriptor - changed layout of all class-specific descriptors - new High Capability descriptors - New class-specific String descriptors - new and removed units - additional sources for interrupts - removed Type II Audio Data Formats - ... and many other things (check spec) It also provides backward compatibility through multiple configurations, as well as requires mandatory support for BADD (Basic Audio Device Definition) on each ADC3.0 compliant device This patch adds initial support of UAC3 specification that is enough for Generic I/O Profile (BAOF, BAIF) device support from BADD document.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

include: usb: audio: specify exact endiannes of descriptors

2017-07-18T06:33:06+00:00

USB spec says that multiple byte fields are stored in little-endian order (see chapter 8.1 of USB2.0 spec and chapter 7.1 of USB3.0 spec), thus mark such fields as LE for UAC1 and UAC2 headers Signed-off-by: Ruslan Bilovol Signed-off-by: Felipe Balbi

ALSA: snd-usb: handle raw data format of UAC2 devices

2013-03-18T07:47:13+00:00

UAC2 compliant audio devices may announce the capability to transport raw audio data on their endpoints. Catch this and handle it as 'special' stream on the ALSA side. Signed-off-by: Daniel Mack Reported-by: Andreas Koch Signed-off-by: Takashi Iwai

ALSA: usb-audio: unify UAC macros and struct names

2010-06-23T14:09:26+00:00

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 Signed-off-by: Takashi Iwai

Also, remove the 'bmControl' field from uac_clock_selector_descriptor, which was at the wrong offset. This struct is currently unused. Signed-off-by: Daniel Mack Signed-off-by: Takashi Iwai
