2014-11-21ASoC: max98095: Replace w->codec snd_soc_dapm_to_codec(w->dapm)Lars-Peter Clausen
The codec field of the snd_soc_widget struct is eventually going to be removed, use snd_soc_dapm_to_codec(w->dapm) instead. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-10ASoC: max98095: Move mutex to the driver levelLars-Peter Clausen
The max98095 uses the snd_soc_codec mutex to protect against concurrent access in some of its control put handlers. Move this mutex to the driver level so we can eventually remove the snd_soc_codec mutex. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-22ASoC: max98095: Cleanup manual bias level transitionsLars-Peter Clausen
Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.

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.

2014-02-20ASoC: 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.

2012-04-01ASoC: max98095: add jack detectionRhyland Klein
This change adds the logic to support using the jack detect mechanism built in to the codec to detect both when a jack was inserted and what type of jack is present. This change also supports the use of an external mechanism for headphone detection. If this mechanism exists, when the max98095_jack_detect function is called, the hp_jack is simply passed NULL. This change supports both simple headphones, powered headphones, microphones and headsets with both headphones and a mic.

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).

2011-12-02ASoC: Drop unused state parameter from CODEC suspend callbackLars-Peter Clausen

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-22ASoC: max98095: Convert codec->hw_write to snd_soc_writeAxel Lin
codec->hw_write is broken now, convert codec->hw_write to snd_soc_write. The hardware has 2 banks of registers sharing a section in I2C register space. The 1st bank is the primary one and is cached. The 2nd bank is for loading coefficients only and they do not need cache. These coefficients registers are therefore direct writes. Thus we set cache_bypass flag to deal with this before calling snd_soc_write.
