2017-08-14ASoC: au1x: constify snd_pcm_ops structuresArvind Yadav1-1/+1
snd_pcm_ops are not supposed to change at runtime. All functions working with snd_pcm_ops provided by <sound/soc.h> work with const snd_pcm_ops. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-01-05ASoC: au1x: Remove unnecessary snd_pcm_lib_preallocate_free_for_all()Lars-Peter Clausen1-6/+0
The ALSA core takes care that all preallocated memory is freed when the PCM itself is freed. There is no need to do this manually in the driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-20ASoC: au1x: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-12-21ASoC: au1x: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen1-9/+0
The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

2012-12-10ASoC: au1x: remove __dev* attributesBill Pemberton1-3/+3
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-01-02ASoC: dbdma2.c: use devm_ functionsJulia Lawall1-10/+4
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc, devm_request_mem_region and devm_ioremap for data that is allocated in the probe function of a platform device and is only freed in the remove function.

2011-07-27ASoC: au1x: remove automatic DMA device registration from PSC driversManuel Lauss1-71/+12
The PSC audio drivers (psc-ac97/psc-i2s) register the DMA platform_device on their own. This is frowned upon, from now on board code must register a simple pcm dma platform device for each PSC with sound duties.

2011-06-07ASoC: core - Optimise and refactor pcm_new() to pass only rtdLiam Girdwood1-3/+4
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.

2010-08-31ASoC: fix au1x platformManuel Lauss1-56/+26
This patch fixes up the au1x audio platform after the multi-component merge: - compile fixes and updates to get DB1200 platform audio working again, - removal of global variables in AC97/I2S/DMA(PCM) modules. The AC97 part is limited to one instance only for now due to issues with getting at driver data in the soc_ac97_ops.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood1-13/+6
This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().
