2013-06-14ASoC: wm8962: Enable start-up and normal bias after reset in runtime resumeNicolin Chen1-0/+11
This part of bias settings are essential for WM8962 to power up. Without it "wm8962 0-001a: DC servo timed out" might be prompted due to power-up failure that happens to FLL if being used. The driver's also bringing the bias down in the suspend path so it needs to be powered up in the resume path for symmetry. According to dapm_pre_sequence_async(), DAPM would call pm_runtime_get_sync() to let driver finish the bias settings in pm_runtime_resume() before the bias level being set to STANDBY. So no need to worry about disordered settings for VMID of WM8962. Signed-off-by: Nicolin Chen <b42378@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

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.

2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood1-3/+3
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).
