* ASoC: soc-cache: Use BUG_ON() for unsupported hw_read() callsDimitris Papastamos2010-11-081-0/+6
| | | | | | | | | Instead of dereferencing a NULL function pointer and falling apart use BUG_ON() for any unimplemented hw_read() calls.

| | | | | | | | | | | | | | | | | | | | | | | | | | The code can't really cope with I/O errors, so it would be better to be consistent throughout all cache functions and return -1 instead of -EINVAL. The return value of snd_soc_read(...) is mostly checked in the probe function and nowhere else.

* | ASoC: Automatically determine control_data for soc-cache usersMark Brown2010-08-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the provision of a struct device for the CODEC is now mandatory we can use container_of() to locate the struct i2c_client and struct spi_device for relevant devices, removing the need to manually set it in each driver. A further patch will automate selection of the control type based on the bus_type of the struct device, further reducing the amount of driver code required.

* | ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood2010-08-121-17/+17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | Add a bit to the CODEC structure indicating if a cache sync is required. By default this will be set if a cache only write is done to a soc-cache register cache.

* ASoC: Allow CODECs to ask soc-cache to suppress physical writesMark Brown2010-02-031-2/+24
| | | | | | | | | | | Currently the soc-cache code will always write to the device, meaning that we need the device to be powered and active at pretty much all times the system is active. Allowing cache only writes lays some groundwork for future enhancements to allow devices to be put into a full off state when the audio subsystem is idle.

* ASoC: Begin to factor out register cache I/O functionsMark Brown2009-07-051-0/+105
A lot of CODECs share the same register data formats and therefore replicate the code to manage access to and caching of the register map. In order to reduce code duplication centralised versions of this code will be introduced with drivers able to configure the use of the common code by calling the new snd_soc_codec_set_cache_io() API call during startup. As an initial user the 7 bit address/9 bit data format used by many Wolfson devices is supported for write only CODECs and the drivers with straightforward register cache implementations are converted to use it.
