* ASoC: codecs: remove __dev* attributesBill Pemberton2012-12-091-4/+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.

* ASoC: wm8996: Move register default configuration to I2C probeMark Brown2012-06-251-151/+180
| | | | | | | This gets the registers set up as early as possible, mainly useful for the GPIOs to ensure that they're in the correct mode. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: wm8996: Inline wm8996_reset() and optimise cache-only usageMark Brown2012-06-251-18/+13Star
| | | | | | | | | | There is only one caller and this allows us to cleanly leave the CODEC with the internal LDO powered down which is the default state we're looking for and means that we can robustly disable the register cache only when we either disable the LDO or power down the external regulators.

| | | | | | | | | When we're not actively doing audio we don't need the microphone biases to be regulated, noise is not important when we are not looking at the audio signal.

* | ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood2012-02-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

|\| | | | | | | | | | | | | | | | | | | | | A reasonable amount of new development is causing fiddly merge conflicts between different resource management changes (mostly fixing bugs in resource management due to noticing things while doing enhancements in the same area). Linux 3.3-rc2 .. several days delayed. No reason, I just didn't think of it.

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

| | | | | | | | | | | | | | | | | | | | | | | | Now that the WM8996 driver is using the regmap API for register I/O we no longer need the ASoC card to be active in order to interact with the chip. In order to be more idiomatic for Linux move most of the existing probe() function out into the I2C probe() function prior to registration with ASoC. The IRQ and GPIO init will be moved separately as these are slightly more involved. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
