2014-08-19ASoC: Consolidate CPU and CODEC DAI lookupLars-Peter Clausen
The lookup of CPU and CODEC DAIs is fairly similar and can easily be consolidated into a single helper function. There are two main differences in the current implementation of the CPU and CODEC DAI lookup: 1) CPU DAIs can be looked up by the DAI name alone and do not necessarily require a component name/of_node. 2) The CODEC DAI search only considers DAIs from CODEC components. For 1) the new helper function will allow to lookup DAIs without providing a component name or of_node, but since snd_soc_register_card() already rejects CODEC DAI link components without neither a of_node or a name we'll never get into the situation where we try to lookup a CODEC DAI without a name/of_node. For 2) the new helper function just always considers all components. Componentization is now at a point where it is possible to register a CODEC as a snd_soc_component rather than a snd_soc_codec, by considering DAIs from all components it is possible to use such a CODEC in a DAI link.

2014-08-19ASoC: Consolidate CPU and CODEC DAI removalLars-Peter Clausen

2014-08-19ASoC: Cleanup DAI module reference countingLars-Peter Clausen
Currently when a DAI has no CODEC associated to it the reference on the module containing the DAI driver is increased when the DAI is probed and decrease when the DAI is removed. For DAIs with CODECs the module reference count was already incremented when the CODEC is probed. Now that all components have their module reference count incremented when they are probed and all DAIs do have a component it is possible to remove the module reference counting on DAI probe and removal.

2014-08-19ASoC: Move component->probed check into soc_{remove,probe}_component()Lars-Peter Clausen
Having the check in a centralized place makes the code a bit cleaner and shorter. Note: There is a slight semantic change in this patch. soc_probe_aux_dev() will no longer return -EBUSY if the AUX dev has already been probed before. This is fine though since it will simply do nothing in that case and return success. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-08-19ASoC: Move AUX dev support to the component levelLars-Peter Clausen
This patch makes it possible to register arbitrary components as a AUX dev for a card. This was previously only possible for CODEC components. With componentization having made it possible for components to have DAPM contexts and controls there is no reason why AUX devs should be artificially limited to snd_soc_codec devices.

2014-08-19ASoC: Add component level probe/remove supportLars-Peter Clausen
Now that we have a unified probe and remove path make sure to call them for all components. soc_{probe,remove}_component are responsible for setting up the DAPM context for the component, initialize the component prefix, manage the debugfs entries as well as do the registration of table based controls and DAPM elements. They also call the component drivers probe and remove callbacks. This patch makes these things available for generic snd_soc_component drivers rather than only having them for snd_soc_codec and snd_soc_platform drivers.

2014-08-19ASoC: Make rtd->codec optionalLars-Peter Clausen
There are some place in the ASoC core that expect rtd->codec to be non NULL (mainly CODEC specific sysfs files). With componentization going forward rtd->codec might be NULL in some cases. This patch prepares the core for this by not registering CODEC specific sysfs files if rtd->codec is NULL. sysfs file removal does not need to be conditionalized as it handles the removal of non-existing files just fine.

2014-08-19ASoC: Consolidate platform and CODEC probe/removeLars-Peter Clausen
The platform and CODEC probe and remove code is now largely identical. This patch consolidates it at the component level. The resulting code is slightly larger due to all the boiler plate code setting up the indirection for the table based control and DAPM registration. Once all drivers have been update to no longer use the snd_soc_codec_driver and snd_soc_platform_driver specific fields for this the indirection can be removed again. This patch contains two noteworthy hacks that are only meant to be temporary to be able to update drivers and the core in separate incremental patches. The first hack is related to that some DPCM platforms expect that the DAPM widgets for the DAIs of a snd_soc_component are created in the DAPM context of the snd_soc_platform that has the same parent device. For handling this the steal_sibling_dai_widgets attribute is introduced. It gets set for snd_soc_platforms that register DAPM elements. When creating the DAI widgets for a component this flag is checked and if it is found on one of the siblings the component will not create any DAI widgets in its own DAPM context. If the attribute is set on a platform it will look for siblings components and create DAI widgets for them in its own context. The fix for this will be to update the offending drivers to only register a single component rather than two. The second hack deals with the fact that the ASoC card suspend and resume code still needs a list of CODECs that have been registered for the card. To handle this the generic probe and remove path have a check to see if the component is CODEC and if yes add/remove it to the card's CODEC list. While it is possible to clean up the suspend/resume code to not need the CODEC list anymore this is a bit of a chicken and egg problem since it will become easier to clean up the suspend/resume code once there is a unified component layer.

2014-08-19ASoC: Move debugfs registration to the component levelLars-Peter Clausen
The debugfs registration is mostly identical between platforms and CODECs. This patches consolidates the two implementations at the component level. Unfortunately there are still a couple of CODEC specific debugfs files that are related to legacy ASoC IO that need to be registered. For this a new callback is added to the component struct that will be initialized when a CODEC is registered and will be used to register the CODEC specific files. Once there are no drivers left using legacy IO this can be removed again. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

And SYNC of TCR2 is a 2-width control bit: 00 Asynchronous mode. 01 Synchronous with receiver. 10 Synchronous with another SAI transmitter. 11 Synchronous with another SAI receiver.

So the driver should have set SYNC bit of TCR2 to 0x0, and meanwhile set SYNC bit of RCR2 to 0x1 (Synchronous with transmitter).

2014-08-16ASoC: fsl_sai: Initialize with software resetNicolin Chen
This patch adds software reset code in dai_probe() so as to make a true init by clearing SAI's internal logic, including the bit clock generation, status flags, and FIFO pointers. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-08-16ASoC: fsl_esai: refine esai for TDM supportShengjiu Wang
Original driver didn't store the number of slots, just fix the slot number to 2, use this default number to calculate bclk and pins for TX/RX. In this patch, add one parameter for slots, and update the calculation of bclk and pins of TX/RX. Then driver will be compatible with slots > 2 in TDM mode.

2014-08-16ASoC: fsl: Add Freescale Generic ASoC Sound Card with ASRC supportNicolin Chen
The Freescale Generic ASoC Sound Card is a general ASoC DAI Link driver that can be used, ideally, for all Freescale CPU DAI drivers and external CODECs. The idea of this generic sound card is a bit like ASoC Simple Card. However, for Freescale SoCs (especially those released in recent years), most of them have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And this is a specific feature that might be painstakingly controlled and merged into the Simple Card driver. So having this driver will allow all Freescale SoC users to benefit from the simplification to support a new card and the capability of wide sample rates support through ASRC. The driver is initially designed for sound card using I2S or PCM DAI formats. However, it's also possible to merge those non-I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, into this card as long as the merge will not break the original function and as long as there is something redundant that can be abstracted along with I2S type sound cards. As an initial version, it only supports three cards that I can test: imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver imx-audio-wm8962, just like the old imx-wm8962.c driver The driver is also compatible with the old Device Tree bindings of WM8962 and SGTL5000. So we may consider to remove those two drivers after this driver is totally enabled.
