* ASoC: Automatically initialize regmap for all componentsLars-Peter Clausen2014-08-191-28/+0
| | | | | | | | | | 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.

* ASoC: Remove ASoC level IO tracingLars-Peter Clausen2014-04-221-11/+0
| | | | | | | | | | | | 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.

* ASoC: Remove snd_soc_update_bits_locked()Lars-Peter Clausen2014-04-221-20/+0
| | | | | | | | 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>
* ASoC: Move IO abstraction to the component levelLars-Peter Clausen2014-04-221-112/+210
| | | | | | | | | | | | | | | | | | | | | 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.

* ASoC: io: Remove support for ASoC cache in conjunction with regmapMark Brown2014-03-191-31/+4

| | | | | | | | | | | | 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.

| | | | | | | | | 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.
