* ASoC: codecs: Remove rtd->codec usage from CODEC driversMark Brown2012-04-04
| | | | | | | | | | In order to support CODEC<->CODEC links remove the assumption that there is only a single CODEC on a DAI link by removing the use of the CODEC pointer in the rtd from the CODEC drivers. They are already being passed their DAI whenever they are passed an rtd and can get the CODEC from there. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: sta32x: Optimize the array work to find rate_min and rate_maxAxel Lin2012-01-03
| | | | | | | | | | For a given ir and fs, there is at most one possible match for the case mclk_ratios[ir][j].ratio * fs == freq. Thus we can break from the inner loop once a match is found.

* ASoC: Drop unused state parameter from CODEC suspend callbackLars-Peter Clausen2011-12-02
| | | | | | | | | | 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.

* ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen2011-11-23
| | | | | | | | | | | | | | | | | | | | | | | 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>
* ASoC: sta32x: add workaround for ESD reset issueJohannes Stezenbach2011-11-14
| | | | | | | | | | sta32x resets and loses all configuration during ESD test. Work around by polling the CONFA register once a second and restore all coeffcients and registers when CONFA changes unexpectedly.

* ASoC: sta32x: add platform data definitionJohannes Stezenbach2011-11-14
| | | | | | | | Add a structure for platform specific configuration and use it, thereby removing a few FIXMEs which marked hard-coded values. Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: sta32x: preserve coefficient RAMJohannes Stezenbach2011-11-14
| | | | | | | | | | The coefficient RAM must be saved in a shadow so it can be restored when the codec is powered on using regulator_bulk_enable(). Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
* ASoC: sta32x: Write the register default value to cache for reserved registersAxel Lin2011-10-13
| | | | | | | | | | | | | | Chip documentation explicitly requires that the reset values of reserved register bits are left untouched. codec->hw_read is broken now. Here we use below trick to avoid writing to reserved registers while resume. Write the register default value to cache for reserved registers, so the write to the these registers are suppressed by the cache restore code when it skips writes of default registers.

* ASoC: sta32x: Move resource allocation and release to the corresponding ↵Axel Lin2011-08-18
| | | | | | | | | | | | | | | | | callback functions This patch includes below small fixes: 1. Move sta32x_set_bias_level() from sta32x_i2c_remove() to sta32x_remove(). 2. Remove a redundant regulator_bulk_free() call in sta32x_i2c_remove(), as we will call regulator_bulk_free() in sta32x_remove(). 3. Remove unneeded snd_soc_codec_set_drvdata(codec, NULL) in sta32x_i2c_remove. The i2c core will set the clientdata to NULL.

* ASoC: sta32x: shortcut the for loop to get ir and mcsAxel Lin2011-08-15

* ASoC: STA32x: Preserve reserved register bitsJohannes Stezenbach2011-07-13
| | | | | | | | | | | Chip documentation explicitly requires that the reset values of reserved register bits are left untouched. It is possible there are differences between STA326 and STA328 or future chip revisions in these bits, and clobbering them might cause malfunction.

* ASoC: STA32x: Add mixer controls for biquad coefficientsJohannes Stezenbach2011-07-13
| | | | | | | | | | | | | | | | | | | The STA32x has a number of preset EQ settings, but also allows full user control of the biquad filter coeffcients (when "Automode EQ" is set to "User"). Each biquad has five signed, 24bit, fixed-point coefficients representing the range -1...1. The five biquad coefficients can be uploaded in one atomic operation into on-chip coefficient RAM. There are also a few prescale, postscale and mixing coefficients, in the same numeric format and range (a negative coefficient inverts phase). These coefficients are made available as SNDRV_CTL_ELEM_TYPE_BYTES mixer controls. Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
