2014-09-06ASoC: Remove table based DAPM/control setup support from snd_soc_platform_driverLars-Peter Clausen1-9/+0
There are no users left and new users should rather use the component_driver struct embedded in the snd_soc_platform_driver struct to do this. E.g.: static const struct snd_soc_platform_driver foobar_driver = { .component_driver = { .dapm_widgets = ..., .num_dapm_widgets = ..., ..., }, ... }; instead of static const struct snd_soc_platform_driver foobar_driver = { .dapm_widgets = ..., .num_dapm_widgets = ..., ... }; This also allows us to remove the steal_sibling_dai_widgets hack.

2014-09-04ASoC: Add support for automatically going to BIAS_OFF on suspendLars-Peter Clausen1-0/+1
There is a substantial amount of drivers that in go to SND_SOC_BIAS_OFF on suspend and go back to SND_SOC_BIAS_SUSPEND on resume (Often this is even the only thing done in the suspend and resume handlers). This patch introduces a new suspend_bias_off flag, which when set by a driver will let the ASoC core automatically put the device's DAPM context at the SND_SOC_BIAS_OFF level during suspend. Once the device is resumed the DAPM context will go back to SND_SOC_BIAS_STANDBY (if the context is idle, otherwise to SND_SOC_BIAS_ON). This will allow us to remove a fair bit of duplicated code from the drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-08-19ASoC: Pass component instead of DAPM context to AUX dev init callbackLars-Peter Clausen1-1/+1

2014-08-19ASoC: Move AUX dev support to the component levelLars-Peter Clausen1-0/+1
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 Clausen1-0/+11
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: Consolidate platform and CODEC probe/removeLars-Peter Clausen1-10/+17
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 Clausen1-5/+15
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>

2014-07-22ASoC: Move card field form platform/codec to componentLars-Peter Clausen1-2/+1
Both the snd_soc_codec and snd_soc_platform struct do have a pointer to the parent card and both handle this pointer in mostly the same way. This patch moves the card field to the component level which will allow further code consolidation between platforms and CODECS. Since there are only a handful of users of the snd_soc_codec struct's card field (and none of the snd_soc_platform's) these are update in this patch as well, which allows it to be removed from the snd_soc_codec struct.

2014-07-16ASoC: core: Add initial support for DAI multicodecBenoit Cousson1-0/+13
DAI link assumes a one to one mapping between CPU DAI and CODEC. In some cases, the same CPU DAI can be connected to several codecs. This is the case for example, if you connect two mono codecs to the same I2S link in order to have a stereo card. The current ASoC implementation does not allow such setup. Add support for DAI links composed of a single CPU DAI and multiple CODECs. Sound cards have to pass the CODECs array in the corresponding DAI link through a new 'snd_soc_dai_link_component' struct. Each CODEC in this array is described in the same manner single CODEC DAIs are (either DT/OF node or codec_name). Multi-codec links are not supported in the case of CODEC to CODEC links. Just print a warning if it happens. Based on an original code done by Misael.

2014-06-21ASoC: Add component level stream_event() and seq_notifier() supportLars-Peter Clausen1-6/+3
This patch adds stream_event() and seq_notifier() callbacks similar to those found in the snd_soc_codec_driver and snd_soc_platform driver struct to the snd_soc_component_driver struct. This is meant to unify the handling of these callbacks across different types of components and will eventually allow their removal from the CODEC and platfrom driver structs. The new callbacks are slightly different from the old ones in that they take a snd_soc_component as a parameter rather than a snd_soc_dapm_context. This was done since otherwise casting from the DAPM context to the component would typically be the first thing to do in the callback. And the interface becomes slightly cleaner by passing a snd_soc_component to all callbacks in the snd_soc_component_driver struct. The patch also already removes the stream_event() callback from the snd_soc_codec_driver and snd_soc_platform_driver structs as it is currently unused.

2014-06-21ASoC: Add DAPM support at the component levelLars-Peter Clausen1-0/+30
This patch adds full DAPM support at the component level. Previously there was only full DAPM support for CODECs and partial DAPM support (e.g. no Mixers nor MUXs) for platforms. Having DAPM support at the component level will allow all types of components to use DAPM and also help in consolidating the DAPM support between CODECs and platforms. Since the DAPM context is directly embedded into the snd_soc_codec and snd_soc_platform struct and the 'dapm' field is directly referenced in a lot of drivers moving the field just right now is not possible without causing code churn. The approach this patch takes is to add two new fields to the component struct. One field which is the pointer to the actual DAPM context used by the component and one DAPM context that will be used as the default if no other context was specified. For CODECs and platforms the pointer is initialized to point to the CODEC or platform DAPM context. All generic code when referencing a component's DAPM struct will go via the pointer. This will make it possible to eventually seamlessly move the DAPM context from snd_soc_codec and snd_soc_platform struct over once all direct references have been eliminated.

Legacy GPIO numbers are used only when GPIO consumer device gpiod_dev is NULL and otherwise idx is the descriptor index within the GPIO consumer device. New function snd_soc_jack_add_gpiods() is added for typical cases where all GPIO descriptor jack pins belong to same GPIO consumer device. For other cases the caller must set the gpiod_dev in struct snd_soc_jack_gpio before calling snd_soc_jack_add_gpios().

2014-04-22ASoC: Move IO abstraction to the component levelLars-Peter Clausen1-7/+24
We currently have two very similar IO abstractions in ASoC, one for CODECs, the other for platforms. Moving this to the component level will allow us to unify those two. It will also enable us to move the standard kcontrol helpers as well as DAPM support to the component level. The new component level abstraction layer is primarily build around regmap. There is a per component pointer for the regmap instance for the underlying device. There are four new function snd_soc_component_read(), snd_soc_component_write(), snd_soc_component_update_bits() and snd_soc_component_update_bits_async(). They have the same signature as their regmap counter-part and will internally forward the call one-to-one to regmap. If the component it not using regmap it will fallback to using the custom IO callbacks. This is done to be able to support drivers that haven't been converted to regmap yet, but it is expected that this will eventually be removed in the future once all component drivers have been converted to regmap.
