2014-06-19ASoC: wm5100/wm8903/wm8996: Replace open-coded snd_soc_dapm_to_codec()Lars-Peter Clausen
We now have a generic helper function to cast from a DAPM context to a CODEC. Make use of it in the places which previously open-coded it.

2014-04-14ASoC: Add snd_soc_kcontrol_codec() helper functionLars-Peter Clausen
For CODEC controls snd_kcontrol_chip() currently returns a pointer to the CODEC that registered the control. With the upcoming consolidation of platform and CODEC controls this will change. Prepare for this by introducing the snd_soc_kcontrol_codec() helper function that will hide the implementation details of how the CODEC for a control can be obtained. This will allow us to change this easily in the future. The patch also updates all CODEC drivers to use the new helper function.

2014-02-25ASoC: wm8996: Replace codec->control_data with wm8996->regmapLars-Peter Clausen
With the ongoing component-ization of the ASoC framework and the continuing migration to using regmap for IO the control_data field of the snd_soc_codec struct will eventually be removed. Prepare the wm8996 driver for this by using wm8996->regmap instead of accessing the CODEC's control_data field.

2014-02-20ASoC: Rename soc_enum.max field with itemsTakashi Iwai
The name "max" in struct soc_enum is rather confusing since it actually takes the number of items. With "max", one might try to assign (nitems - 1) value. Rename the field to a more appropriate one, "items", which is also used in struct snd_ctl_elem_info, too. This patch also rewrites some code like "if (x > e->nitems - 1)" with "if (x >= e->nitems)". Not only the latter improves the readability, it also fixes a potential bug when e->items is zero.

2013-11-07ASoC: wm8996: Replace BUG() with WARN()Takashi Iwai
BUG() used in the driver is just to spit the stack trace on buggy points, not really needed to stop the whole operation. For that purpose, it'd be more convenient to use WARN() instead with more error information.

2012-06-25ASoC: wm8996: Move register default configuration to I2C probeMark Brown

2012-06-25ASoC: wm8996: Inline wm8996_reset() and optimise cache-only usageMark Brown
There is only one caller and this allows us to cleanly leave the CODEC with the internal LDO powered down which is the default state we're looking for and means that we can robustly disable the register cache only when we either disable the LDO or power down the external regulators.

2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood
Currently ASoC can only add kcontrols using codec and platform component device handles. It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for SoC card machine drivers too. This allows the kcontrol to have a direct handle to the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily get it's private data. This change makes snd_soc_add_controls() static and wraps it in the folowing calls (card and dai are new) :- snd_soc_add_card_controls() snd_soc_add_codec_controls() snd_soc_add_dai_controls() snd_soc_add_platform_controls() This patch also does a lot of small mechanical changes in individual codec drivers to replace snd_soc_add_controls() with snd_soc_add_codec_controls(). It also updates the McBSP DAI driver to use snd_soc_add_dai_controls(). Finally, it updates the existing machine drivers that register controls to either :- 1) Use snd_soc_add_card_controls() where no direct codec control is required. 2) Use snd_soc_add_codec_controls() where there is direct codec control. In the case of 1) above we also update the machine drivers to get the correct component data pointers from the kcontrol (rather than getting the machine pointer via the codec pointer).
