2014-02-23ASoC: tlv320aic32x4: Rearrange clock tree shutdownMarkus Pargmann1-16/+16
Rearrange clock tree shutdown to disable them in the reversed order of startup. First disable all dividers, then PLL followed by master clock. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-23ASoC: tlv320aic32x4: Support for regulatorsMarkus Pargmann1-1/+125
Support regulators to power up the codec. This patch also enables the AVDD LDO if no AV regulator was found. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-23ASoC: tlv320aic32x4: Support for master clockMarkus Pargmann1-0/+21
Add support for a master clock passed through DT. The master clock of the codec is only active when the codec is in use. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: tlv320aic32x4: DT supportMarkus Pargmann1-0/+25
Add DT support for this codec. The bindings differ a bit from the aic3x codec bindings, so I created a new binding documentation. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: tlv320aic32x4: Use signed int mixer controlsMarkus Pargmann1-10/+16
There are a number of mixer controls that support negative values. They use signed values for this with different number of bits for the values. Currently they only support the positive range. This patch replaces the unsigned mixers with signed mixers to support the full range. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: tlv320aic32x4: Use gpio_is_validMarkus Pargmann1-2/+2
Use function gpio_is_valid to check for gpio ports. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-01-27ASoC: tlv320aic32x4: Fix MICPGA input configurationMarkus Pargmann1-4/+6
Currently the Negative Terminal Input Routing Configuration is only set when there is a special routing configuration. If we don't use one of the inputs IN1 or IN2 as negative terminal input, the PGA and recording does not work. This patch adds a route from CM1L/CM1R to the PGA as negative input by default. With this configuration the PGA can amplify all input signals and line-in/mic works again. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-01-27ASoC: tlv320aic32x4: Fix mono playbackMarkus Pargmann1-7/+11
Playback of a mono stream should output the same stream on both channels. At the moment only the left analog signal is valid, the right one is just noise. This patch maps the left digital channel onto both DACs when receiving a mono stream. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-01-16ASoC: tlv320aic32x4: Fix regmap range_minMarkus Pargmann1-1/+1
range_min is the lowest address in the virtual register range. This is the first register with address 0, not the first register of page 1. Currently all writes to page 1 are mapped to page 0, so the codec fails to operate.

2014-01-13ASoC: codec: tlv320aic32x4: Fix regmap range configMarkus Pargmann1-1/+1
This codec driver fails to probe because it has a higher regmap range_max value than max_register. This patch sets the range_max to the max_register value as described in the for struct regmap_range_cfg: "@range_max: Address of the highest register in virtual range."

2013-09-26ASoC: tlv320aic32x4: Convert to direct regmap API usageMark Brown1-66/+23
This moves us towards being able to remove the duplicate register I/O functionality in ASoC and saves some code. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-26ASoC: tlv320aic32x4: Move GPIO acquisition to I2C probeMark Brown1-5/+7
This is more idiomatic and interacts better with deferred probe. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-08-27ASoC: tlv320aic32x4: Convert table based control and DAPM setupLars-Peter Clausen1-15/+7

2012-12-09ASoC: codecs: remove __dev* attributesBill Pemberton1-4/+4
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-01ASoC: tlv320aic32x4: Add rstn gpio to platform data.Javier Martin1-0/+14
Add the possibility to specify a gpio through platform data so that a HW reset can be issued to the codec. Signed-off-by: Javier Martin <javier.martin@vista-silicon.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-01ASoC: tlv320aic32x4: Fix problem with first capture.Javier Martin1-0/+10
In its previous status, the first capture didn't work properly; nothing was actually recorded from the microphone. This behaviour was observed using a Visstrim M10 board. In order to solve this BUG a workaround has been added that, during the initialization process of the codec, powers on and off the ADC. The issue seems related to a HW BUG or some behavior that is not documented in the datasheet.

2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood1-1/+1
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 Clausen1-1/+1
The existence of this parameter is purely historical. None of the CODEC drivers uses it and we always pass in the same value anyway, so it should be safe to remove it.

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>
