2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood1-3/+3
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).

2012-01-28ASoC: wm8962: Enable idle_bias_offMark Brown1-0/+1
The WM8962 has ground referenced and class D outputs so can happily go down to BIAS_OFF without a large startup time. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-01-26ASoC: wm8962: Mark register cache as dirty when regulators are disabledMark Brown1-1/+1
Otherwise we won't resync later. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-01-25ASoC: wm8962: Optimise power consumption for IN4 DC measurement usageMark Brown1-0/+18
When the hardware is configured with one or both of the IN4 inputs used for DC measurement (with no DC blocking capacitor connected) then we can improve power consumption slightly in idle modes by applying a register write sequence. Provide platform data to enable this, implemented using a regmap patch. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-01-20ASoC: Add WM8962 DAC and ADC L/R swap supportMark Brown1-0/+2

2012-01-20ASoC: Convert WM8962 register access map to modern styleMark Brown1-1155/+648

2012-01-20ASoC: Make WM8962 I2C usage unconditionalMark Brown1-13/+1

2012-01-02ASoC: Fix return value of wm8962_gpio_direction_out()Axel Lin1-3/+7
We can't just pass back the return value of snd_soc_update_bits() as it will be 1 if a bit changed rather than zero. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen1-1/+1
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>

2011-11-08ASoC: Convert WM8962 to direct regmap usageMark Brown1-791/+802
This initial conversion just moves the register init, regulator acquisition and device verification out to the I2C probe(). Movement of other parts of the driver like the GPIO and beep generation code will follow. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-11-01ASoC: WM8962 accessory detection requires MICBIASMark Brown1-1/+3
