2016-02-23ALSA: jack: Allow building the jack layer without input deviceTakashi Iwai
Since the recent integration of kctl jack and input jack layers, we can basically build the jack layer even without input devices. That is, the jack layer itself can be built with conditional to enable the input device support or not, while the users may enable always CONFIG_SND_JACK unconditionally. For achieving it, this patch changes the following: - A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate whether the jack layer supports the input device, - A few items in snd_jack struct and relevant codes are conditionally built upon CONFIG_SND_JACK_INPUT_DEV, - The users of CONFIG_SND_JACK drop the messy dependency on CONFIG_INPUT. This change also automagically fixes a potential bug in HD-audio driver Arnd reported, where the NULL or uninitialized jack instance is dereferenced.

ACP IP has internal DMA controller with multiple channels which can be programmed in cyclic/non cyclic manner. ACP can generate interrupt upon completion of DMA transfer, if required. The PCM driver provides the platform DMA component to ALSA core.

2015-09-16ASoC: sunxi: add support for the on-chip codec on early Allwinner SoCsEmilio López
The sun4i, sun5i and sun7i SoC families have a built-in codec, capable of both audio capture and playback. While this is called a codec by Allwinner, it really is an in-SoC combination of a codec and a DAI, with its own DAC/ADC and amplifiers in a single memory-mapped controller. The capture part has been left out for now, and will be added eventually.

Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

2013-12-09ASoC: Add support for the Analog Devices AXI-I2S coreLars-Peter Clausen
This patch adds support for the AXI-I2S softcore. The core implements a simple bidirectional I2S transceiver and is used by Analog Devices in some of their reference designs for various FPGA platforms. The driver uses the generic PCM dmaengine driver for its PCM. The only restriction is that we need to set the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag as the dmaengine driver for the DMA core (PL330) that is used with this core has no residue reporting capabilities yet.

2010-11-11ASoC: soc-cache: Add support for LZO register cachingDimitris Papastamos
This patch adds support for LZO compression when storing the register cache. The initial register defaults cache is marked as __devinitconst and the only change required for a driver to use LZO compression is to set the compress_type member in codec->driver to SND_SOC_LZO_COMPRESSION. For a typical device whose register map would normally occupy 25kB or 50kB by using the LZO compression technique, one can get down to ~5-7kB. There might be a performance penalty associated with each individual read/write due to decompressing/compressing the underlying cache, however that should not be noticeable. These memory benefits depend on whether the target architecture can get rid of the memory occupied by the original register defaults cache which is marked as __devinitconst. Nevertheless there will be some memory gain even if the target architecture can't get rid of the original register map, this should be around ~30-32kB instead of 50kB.

This patch adds a jack reporting interface to ASoC.

Since embedded platforms can have multiple detecton methods used for a single jack (eg, separate microphone and headphone detection) the report function allows specification of which bits are being updated on a given report. The expected usage is that machine drivers will create jack objects and then configure jack detection methods to update that jack. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
