Subject: [PATCH 082/104] ASoC: OMAP4 ABE DSP - Add support for the OMAP4 ABE DSP

2012-08-17T08:18:26+00:00

This patch adds the OMAP4 ABE platform driver. This driver defines and
exports control for the DSP Frontend and Backend routing.

TODO: cleanup

Subject: [PATCH 078/104] ASoC: dsp - add core support for bespoke trigger()

2012-08-17T08:18:26+00:00

This allows the DSP core to call a beskope trigger() call
on DAIs and platforms that require it.

TODO: move into DSP patch series.

Subject: [PATCH 077/104] ASoC: core - add hostless DAI support

2012-08-17T08:18:26+00:00

Allow DAI's to be hostless so that no PCM data is sent between DAI
and CPU. This allows for power savings as there is no DMA or CPU
interaction required.

TODO: we shouldn't need to allocate a PAGE for a dummy DMA buffer.

Subject: [PATCH 075/104] ALSA: pcm - add support for hostless audio

2012-08-17T08:18:25+00:00

Allow some PCM devices to be hostless, i.e. there is no PCM data transferred
to or from the host CPU. This can be used to minimise power on systems since
the CPU can idle/sleep during the PCM device operation (e.g. a phone call
where the DAI is between a MODEM and DSP)

TODO: cleanup, look at adding a read/write blocker.

Subject: [PATCH 074/104] ASoC: core - add dynamic kcontrols

2012-08-17T08:18:25+00:00

TODO: First phase of dynamic kcontrols. More todo.

Subject: [PATCH 071/104] ASoC: dsp - Add DSP support to core ASoC API/structures

2012-08-17T08:18:25+00:00

Export inline DAI PCM operations to allow DSP core to individually call BE PCM
operations and ....

Allow machine drivers to specifify DSP FE and BE DAI links.
Add FE and BE state information to PCM rtd.

TODO: split out this into smaller patches.

Subject: [PATCH 070/104] ASoC: dsp - Add ASoC DSP core

2012-08-17T08:18:24+00:00

This adds ASoC core support for internal and external DSPs and represents them
to the audio user as a CODEC like device with mixers, muxes and runtime audio
route changing.

The DSP core allows DSP 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).

The DSP core also deal with DSP FE+BE suspend and resume PM ops.

Subject: [PATCH 069/104] ASoC: dapm - allow custom widgets to update power events.

2012-08-17T08:18:24+00:00

In preparation for ASoC DSP support.

Allow for the operation of custom mixer and mux DAPM widgets that can call
snd_soc_dapm_mixer_update_power() and snd_soc_dapm_mux_update_power() directly
after updating their status.

This adds two previously static calls to the public DAPM API.

Subject: [PATCH 068/104] ASoC: dapm - Add API call to query valid DAPM paths.

2012-08-17T08:18:24+00:00

In preparation for ASoC DSP support.

Add a DAPM API call to determine whether a DAPM audio path is valid between
source and sink widgets. This also takes into account all kcontrol mux and mixer
settings in between the source and sink widgets to validate the audio path.

This will be used by the DSP core to determine the runtime DAI mappings
between FE and BE DAIs in order to run PCM operations.

Subject: [PATCH 067/104] ASoC: dapm - Add DAPM stream completion event.

2012-08-17T08:18:24+00:00

In preparation for ASoC DSP support.

This adds a callback function to be called at the completion of a DAPM stream
event.

This can be used by DSP components to perform calculations based on DAPM graphs.
