2017-11-08ASoC: add snd_soc_component_read32Kuninori Morimoto
Current codec drivers are using snd_soc_read(). It will be replaced into snd_soc_component_read(), but these 2 are using different style. For example, it will be - val = snd_soc_read(xxx, reg); + ret = snd_soc_component_read(xxx, reg, &val); + if (ret < 0) { + ... + } To more smooth replace, let's add snd_soc_component_read32 which is copied from snd_soc_read() - val = snd_soc_read(xxx, reg); + val = snd_soc_component_read32(xxx, reg); Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-08-19ASoC: Automatically initialize regmap for all componentsLars-Peter Clausen
So far regmap is only automatically initialized for CODECs. Now that we have the infrastructure in place to let components have DAPM widgets and controls that want to use the generic regmap based IO also make sure to automatically initialize regmap for all components.

2014-04-22ASoC: Remove ASoC level IO tracingLars-Peter Clausen
The ASoC framework is in the process of migrating all IO operations to regmap. regmap has its own more sophisticated tracing infrastructure for IO operations, which means that the ASoC level IO tracing becomes redundant, hence this patch removes them. There are still a handful of ASoC drivers left that do not use regmap yet, but hopefully the removal of the ASoC IO tracing will be an additional incentive to switch to regmap.

2014-04-22ASoC: Remove snd_soc_update_bits_locked()Lars-Peter Clausen
There are no users of snd_soc_update_bits_locked() left and it is identical to snd_soc_update_bits(). So it can be removed. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-04-22ASoC: Move IO abstraction to the component levelLars-Peter Clausen
We currently have two very similar IO abstractions in ASoC, one for CODECs, the other for platforms. Moving this to the component level will allow us to unify those two. It will also enable us to move the standard kcontrol helpers as well as DAPM support to the component level. The new component level abstraction layer is primarily build around regmap. There is a per component pointer for the regmap instance for the underlying device. There are four new function snd_soc_component_read(), snd_soc_component_write(), snd_soc_component_update_bits() and snd_soc_component_update_bits_async(). They have the same signature as their regmap counter-part and will internally forward the call one-to-one to regmap. If the component it not using regmap it will fallback to using the custom IO callbacks. This is done to be able to support drivers that haven't been converted to regmap yet, but it is expected that this will eventually be removed in the future once all component drivers have been converted to regmap.

2014-04-14ASoC: core: Move the default regmap I/O setting to snd_soc_register_codec()Xiubo Li
Add the default regmap I/O setting to snd_soc_register_codec() while the CODEC is initialising, which will be called by CODEC driver device probe(), and then we can make XXX_set_cache_io() go away entirely from each CODEC ASoC probe.

2014-03-19ASoC: io: Remove support for ASoC cache in conjunction with regmapMark Brown
Since all regmap CODECs should be (and are) using the more advance regmap cache infrastructure remove the code which supports that and just proxy I/O straight through to regmap. Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-11ASoC: io: New signature for snd_soc_codec_set_cache_io()Xiubo Li
Now that all users have been converted to regmap and the config.reg_bits and config.val_bits can be setted by each user through regmap core API. So these two params are redundant here. Since the only control type that left is SND_SOC_REGMAP, so remove it. Drop the control params and add struct regmap *regmap to simplify the code.

2014-02-16ASoC: io: Remove SPI supportMark Brown

2012-02-21ASoC: io: Retrieve val_bytes from the regmap APIMark Brown
Allow us to build infrastructure which needs to know the size of a value without requiring regmap based drivers to supply this information to both ASoC and regmap by asking regmap for the value. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2012-01-21ASoC: Use regmap update bits operation for drivers using regmapMark Brown
If a driver is using regmap directly ensure that we're coherent with non-ASoC register updates by using the regmap API directly to do our read/modify/write cycles. This will bypass the ASoC cache but drivers using regmap directly should not be using the ASoC cache. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-31sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker

2011-10-09ASoC: Squash error codes from regmap down to -1 on readMark Brown

2011-08-14ASoC: Support !CONFIG_REGMAP buildsMark Brown

2011-08-12ASoC: soc-io: Fix CONFIG_REGMAP_I2C/SPI guards to support regmap modulesStephen Warren
When CONFIG_REGMAP_I2C/SPI are m, CONFIG_REGMAP_I2C_MODULE is set in the pre-processor instead of CONFIG_REGMAP_I2C. This removes SND_SOC_I2C as a valid option for snd_soc_codec_set_cache_io()'s control parameter, and causes any ASoC regmap-using codec built as a module to fail to initialize.

2011-08-08ASoC: Add regmap as a control typeMark Brown

2011-08-08ASoC: Use new register map API for ASoC generic physical I/OMark Brown
Remove all the ASoC specific physical I/O code and replace it with calls into the regmap API. The bulk write code can only be used safely if all regmap calls are locked with the CODEC lock, we need to add bulk support to the regmap API or replace the code with an open coded loop (though currently it has no users...).
