2008-01-31[ALSA] soc - Don't lock the codec list in snd_soc_dapm_new_widgets()Mark Brown
snd_soc_dapm_new_widgets() takes the codec lock when adding new widgets, causing lockdep warnings when applications later call down through ALSA to adjust controls. Since widgets are only added during probe this lock should be unneeded so don't take it. Thanks to Dmitry Baryshkov <dbaryshkov@gmail.com> for reporting this issue.

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2007-10-16[ALSA] alsa-kernel: schedule_timeout() fixesRene Herman
Fix schedule_timeout() use in alsa-kernel. Mostly just schedule_timeout(1) --> schedule_timeout_uninterruptible(1) The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main, delete a superfluous set_current_state() and in soc/soc-dapm.c replace an _interruptible with _uninterruptible in some debug code; it's not waiting for signals.

2007-05-11[ALSA] ASoC DAPM switching for reentrant codec pathsSeth Forshee
This patch fixes an issue whereby power was applied to any inactive analog path that would leave and reenter a codec (e.g. ACOP -> ACIN on WM8753). This change now checks for such paths and DAPM will power them down when not in use.

2007-02-09[ALSA] ASoC: dynamic audio power management (DAPM)Richard Purdie
This patch adds Dynamic Audio Power Management (DAPM) to ASoC. Dynamic Audio Power Management (DAPM) is designed to allow portable and handheld Linux devices to use the minimum amount of power within the audio subsystem at all times. It is independent of other kernel PM and as such, can easily co-exist with the other PM systems. DAPM is also completely transparent to all user space applications as all power switching is done within the ASoC core. No code changes or recompiling are required for user space applications. DAPM makes power switching decisions based upon any audio stream (capture/playback) activity and audio mixer settings within the device. DAPM spans the whole machine. It covers power control within the entire audio subsystem, this includes internal codec power blocks and machine level power systems. There are 4 power domains within DAPM:- 1. Codec domain - VREF, VMID (core codec and audio power) Usually controlled at codec probe/remove and suspend/resume, although can be set at stream time if power is not needed for sidetone, etc. 2. Platform/Machine domain - physically connected inputs and outputs Is platform/machine and user action specific, is configured by the machine driver and responds to asynchronous events e.g when HP are inserted 3. Path domain - audio subsystem signal paths Automatically set when mixer and mux settings are changed by the user. e.g. alsamixer, amixer. 4. Stream domain - DAC's and ADC's. Enabled and disabled when stream playback/capture is started and stopped respectively. e.g. aplay, arecord. All DAPM power switching decisions are made automatically by consulting an audio routing map of the whole machine. This map is specific to each machine and consists of the interconnections between every audio component (including internal codec components).
