Takashi Iwai	79c7cdd544	ALSA: Add kernel-doc comments to vmaster stuff ... Signed-off-by: Takashi Iwai <tiwai@suse.de>	2009-03-09 15:10:01 +01:00
Takashi Iwai	f5b1db6342	ALSA: add snd_ctl_add_slave_uncached() ... Added snd_ctl_add_slave_uncached() function to add a slave element with volatile controls. The values of normal slave elements are supposed to be cachable, i.e. they are changed only via the put callbacks. OTOH, when a slave element is volatile and its values may be changed by other reason (e.g. hardware status change), the values will get inconsistent. The new function allows the slave elements with volatile changes. When the slave is tied with this call, the native get callback is issued at each time so that the values are always updated.

Takashi Iwai	1c82ed1bc5	[ALSA] Keep private TLV entry in vmaster itself ... Use a private array for TLV entries of virtual master controls instead of (supposed) static array. This cleans up the existing codes. Also, now vmaster assumes the simple dB-range TLV that is the only type it can handle. Signed-off-by: Takashi Iwai <tiwai@suse.de>	2008-04-24 12:00:12 +02:00
Takashi Iwai	e922b0028f	[ALSA] Move vmaster code to sound core ... Move the codes for virtual master controls to sound core part so that not only hda-intel drivers can use it. Signed-off-by: Takashi Iwai <tiwai@suse.de>	2008-04-24 12:00:12 +02:00
