ALSA: line6: Split to each driver

2015-01-20T07:14:17+00:00

Split to each individual driver for POD, PODHD, TonePort and Variax
with a core LINE6 helper module.  The new modules follow the standard
ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd,
snd-usb-toneport and snd-usb-variax, together with the corresponding
CONFIG_SND_USB_* Kconfig items.

ALSA: move line6 usb driver into sound/usb

2015-01-12T21:29:57+00:00

Promote line6 driver from staging to sound/usb/line6 directory, and
maintain through sound subsystem tree.

This commit just moves the code and adapts Makefile / Kconfig.
The further renames and misc cleanups will follow.

ALSA: usb-audio: Scarlett mixer interface for 6i6, 18i6, 18i8 and 18i20

2014-11-13T06:32:39+00:00

This code contains the Scarlett mixer interface code that was originally
written by Tobias Hoffman and Robin Gareus. Because the device doesn't
properly implement UAC2 this code adds a mixer quirk for the device.

Changes from the original code include removing the metering code along with
dead code and comments. Compiler warnings were fixed. The code to initialize
the sampling rate was causing a crash this was fixed as discussed on the
mailing list. Error, and info messages were convered to dev_err and dev_info
interfaces. The custom scarlett_mixer_elem_info struct was replaced with the
more generic usb_mixer_elem_info to be able to recycle more code from mixer.c.

This patch also makes additional modifications based on upstream comments.
Individual control creation functions are removed and a generic
function is no used. Macros for function calls are removed to improve
readability. Hardcoded control initialization is removed. Save to HW
functionality has been removed. Strings for enums are created dynamically for
the mixer. Strings used for controls are now SNDRV_CTL_ELEM_ID_NAME_MAXLEN
length.

ALSA: MIDI driver for Behringer BCD2000 USB device

2014-04-07T14:05:41+00:00

This patch adds initial support for the Behringer BCD2000 USB DJ controller.
At the moment, only the MIDI part of the device is working, i.e. knobs,
buttons and LEDs.

I also plan to add support for the audio part, but I assume that this will
require more effort than the rather simple MIDI interface. Progress can be
tracked at https://github.com/anyc/snd-usb-bcd2000.

ALSA: snd-usb: re-order code

2011-09-14T15:07:02+00:00

Move code from endpoint.c into a new file called stream.c and rename
functions so that their names actually reflect what they're doing.

This way, endpoint.c will be available to functions that hold all the
endpoint logic.

ALSA: usb-audio: parse clock topology of UAC2 devices

2010-05-31T16:16:59+00:00

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.
