2011-06-13ASoC: Remove unused and about to be broken SND_SOC_CUSTOM I/O busMark Brown1-2/+1
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 Brown1-0/+2
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 Girdwood1-0/+8
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 Girdwood2-0/+22
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.

2011-06-07ASoC: core - Optimise and refactor pcm_new() to pass only rtdLiam Girdwood1-2/+1
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.

2011-06-06ASoC: Add context parameter to card DAPM callbacksMark Brown1-0/+2
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 Brown2-5/+5
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 Warren1-0/+6
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.

2011-03-25ALSA: vmalloc buffers should use normal mmapBenjamin Herrenschmidt1-3/+1
It's a big no-no to use pgprot_noncached() when mmap'ing such buffers into userspace since they are mapped cachable in kernel space. This can cause all sort of interesting things ranging from to garbled sound to lockups on various architectures. I've observed that usb-audio is broken on powerpc 4xx for example because of that. Also remove the now unused snd_pcm_lib_mmap_noncached(). It's an arch business to know when to use uncached mappings, there's already hacks for MIPS inside snd_pcm_default_mmap() and other archs are supposed to use dma_mmap_coherent(). (See my separate patch that adds dma_mmap_coherent() to powerpc) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Add a function to dynamically replace a given control. If the control does not already exist, a third parameter is used to determine whether to actually add that control.
