*	ALSA: topology: Export ID types for TLV controls.	Liam Girdwood	2015-06-04	1	-14/+1
\| \| \| \| \| \| \| \| \|	Make sure userspace can define TLV controls for topology using the correct type numbers and channel mappings. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
*	ALSA: Add comment for control TLV API	David Henningsson	2013-05-08	1	-1/+5
\| \| \| \| \| \| \| \|	Userspace is not meant to have to handle all strange dB ranges, so add a specification comment. Signed-off-by: David Henningsson <david.henningsson@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
*	ALSA: PCM: channel mapping API implementation	Takashi Iwai	2012-09-06	1	-0/+8
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch implements the basic data types for the standard channel mapping API handling. - The definitions of the channel positions and the new TLV types are added in sound/asound.h and sound/tlv.h, so that they can be referred from user-space. - Introduced a new helper function snd_pcm_add_chmap_ctls() to create control elements representing the channel maps for each PCM (sub)stream. - Some standard pre-defined channel maps are provided for convenience.

*	ALSA: tlv: add DECLARE_TLV_DB_RANGE()	Clemens Ladisch	2012-07-16	1	-0/+4
\| \| \| \| \| \| \| \| \|	Add a DECLARE_TLV_DB_RANGE() macro so that dB range information can be specified without having to count the items manually for TLV_DB_RANGE_HEAD(). Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
*	ALSA: tlv: add DECLARE_TLV_CONTAINER()	Clemens Ladisch	2012-07-16	1	-0/+5
\| \| \| \| \| \| \| \|	Add the DECLARE_TLV_CONTAINER() macro to allow having static TLVs containing more than one item. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
*	ALSA: tlv: compute TLV_*_ITEM lengths automatically	Clemens Ladisch	2012-07-16	1	-8/+12
\| \| \| \| \| \| \| \| \| \|	Add helper macros with a little bit of preprocessor magic to automatically compute the length of a TLV item. This lets us avoid having to compute this by hand, and will allow to use items that do not use a fixed length.

*	ALSA: tlv - Define numbers in sound/tlv.h	Takashi Iwai	2010-10-17	1	-1/+3

*	ALSA: Add new TLV types for dBwith min/max	Takashi Iwai	2009-06-17	1	-0/+14
\| \| \| \| \| \| \| \| \| \| \|	Add new types for TLV dB scale specified with min/max values instead of min/step since the resolution can't match always with the one a device provides. For example, usb audio devices give 1/256 dB resolution while ALSA TLV is based on 1/100 dB resolution. The new min/max types have less problems because the possible rounding error happens only at min/max. Signed-off-by: Takashi Iwai <tiwai@suse.de>

*	[ALSA] Add definition of TLV dB range compound	Takashi Iwai	2006-09-23	1	-8/+15
\| \| \| \| \| \| \| \| \|	Added the definition of TLV dB range compound. It contains one or more dB-range or linear-volume TLV entries with min/max ranges. Used for volume controls with non-linear curves. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
*	[ALSA] Add the definition of linear volume TLV	Takashi Iwai	2006-09-23	1	-0/+10
\| \| \| \| \| \| \| \|	Added the definition of linear volume TLV type. Some DSP chips and codecs (e.g. AK codec) use linear volume control. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
*	[ALSA] Control API - TLV implementation for additional information like dB scale	Jaroslav Kysela	2006-09-23	1	-0/+43
	This patch implements a TLV mechanism to transfer an additional information like dB scale to the user space. The types might be extended in future. Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
