| | | | | | | | | | | | | | | For CODEC controls snd_kcontrol_chip() currently returns a pointer to the CODEC that registered the control. With the upcoming consolidation of platform and CODEC controls this will change. Prepare for this by introducing the snd_soc_kcontrol_codec() helper function that will hide the implementation details of how the CODEC for a control can be obtained. This will allow us to change this easily in the future. The patch also updates all CODEC drivers to use the new helper function.

* ALSA: ASoC: cs4271: add optional soft reset workaroundDaniel Mack2012-12-241-0/+34
| | | | | | | | | | | | | | | | | The CS4271 requires its LRCLK and MCLK to be stable before its RESET line is de-asserted. That also means that clocks cannot be changed without putting the chip back into hardware reset, which also requires a complete re-initialization of all registers. One (undocumented) workaround is to assert and de-assert the PDN bit in the MODE2 register. This patch adds a new flag to both the DT bindings as well as to the platform data to enable that workaround.

* ASoC: codecs: Remove rtd->codec usage from CODEC driversMark Brown2012-04-041-2/+1
| | | | | | | | | | 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: core: Add support for DAI and machine kcontrols.Liam Girdwood2012-02-041-1/+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).
