2011-06-30ALSA: sb16 - Fix build errors on MIPS and others with 13bit ioctl sizeTakashi Iwai
One of ioctl definition in sound/sb16_csp.h contains the data size over 8kB, and this causes build errors on architectures like MIPS, which define _IOC_SIZEBITS=13. For avoiding this build errors but keeping the compatibility, manually expand with _IOC() instead of using _IOW() for the problematic ioctl. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-06-14ALSA: rawmidi - Use workq for event handlingTakashi Iwai
Kill tasklet usage in rawmidi core code. Use workq for the event callback instead of tasklet (which is used only in core/seq/seq_midi.c). Signed-off-by: Takashi Iwai <tiwai@suse.de>

Trival fixup for move of I/O code into separate file. Conflicts: sound/soc/soc-cache.c
2011-06-13ASoC: Remove unused and about to be broken SND_SOC_CUSTOM I/O busMark Brown
This will be removed in -next so let's drop it from mainline as soon as we can in order to minimise surprises. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-06-13ASoC: Add weak routes for sidetone style pathsMark Brown
Normally DAPM will power up any connected audio path. This is not ideal for sidetone paths as with sidetone paths the audio path is not wanted in itself, it is only desired if the two paths it provides a sidetone between are both active. If the sidetone path causes a power up then it can be hard to minimise pops as we first power up either the sidetone or the main output path and then power the other, with the second power up potentially introducing a DC offset. Address this by introducing the concept of a weak path. If a path is marked as weak then DAPM will ignore that path when walking the graph, though all the relevant controls are still available to the application layer to allow these paths to be configured.

2011-06-09ASoC: core - PCM mutex per rtdLiam Girdwood
In preparation for the new ASoC Dynamic PCM support (AKA DSP support). The new ASoC Dynamic PCM core allows DAIs to be dynamically re-routed at runtime between the PCM device end (or Frontend - FE) and the physical DAI (Backend - BE) using regular kcontrols (just like a hardware CODEC routes audio in the analog domain). The Dynamic PCM core therefore must be able to call PCM operations for both the Frontend and Backend(s) DAIs at the same time. Currently we have a global pcm_mutex that is used to serialise the ASoC PCM operations. This patch removes the global mutex and adds a mutex per RTD allowing the PCM operations to be reentrant and allow control of more than one DAI at at time. e.g. a frontend PCM hw_params() could configure multiple backend DAI hw_params() with similar or different hw parameters at the same time.

2011-06-07ASoC: core - Allow components to probe/remove in sequence.Liam Girdwood
Some ASoC components depend on other ASoC components to provide clocks and power resources in order to probe() and vice versa for remove(). Allow components to be ordered so that components can be probed() and removed() in sequences that conform to their dependencies. Signed-off-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-06-07ASoC: core - Optimise and refactor pcm_new() to pass only rtdLiam Girdwood
Currently pcm_new() passes in 3 arguments :- card, pcm and DAI. Refactor this to only pass in 1 argument (i.e. the rtd) since struct rtd contains card, pcm and DAI along with other members too that are useful too. Signed-off-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-06-06ASoC: Add context parameter to card DAPM callbacksMark Brown
The card callback will get called for each DAPM context in the card so it can be useful for it to know which device is currently undergoing a transition. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-06-06ASoC: Specify target bias state directly as a bias stateMark Brown
Rather than a simple flag to say if we want the DAPM context to be at full power specify the target bias state. This should have no current effect but is a bit more direct and so makes it easier to change our decisions about the which bias state to go into in future.

2011-05-03ASoC: Store a list of widgets in a DAPM mux/mixer kcontrolStephen Warren
A future change will allow multiple widgets to be affected by the same control. For example, a single register bit that controls separate muxes in both the L and R audio paths. This change updates the code that handles relevant controls to be able to iterate over a list of affected widgets. Note that only the put functions need significant modification to implement the iteration; the get functions do not need to iterate, nor unify the results, since all affected widgets reference the same kcontrol. When creating the list of widgets, always create a 1-sized list, since the control sharing is not implemented in this change.
