* | ASoC: Initial WM8962 DSP2 supportMark Brown2011-08-22
| | | | | | | | | | | | | | | | | | | | | | The WM8962 features a DSP providing a number of signal processing features including HD Bass and Virtual Surround Sound (VSS). Enable initial support for this, allowing users to enable and disable the algorithms using the default coefficient sets. Further patches will add support for runtime configuration of the DSP coefficients. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

* ASoC: Acknowledge WM8962 interrupts before acting on themMark Brown2011-07-20
| | | | | | | | | This closes the small race between a status being read in response to an interrupt and clearing the interrupt, meaning that if the status changes between those periods we might not get a reassertion of the interrupt.

| | | | | | | | | | | | | | | | | | We really should be getting the interrupt - if we don't get one it's very likely that the configuration is incorrect and audio will fail.

* ASoC: Implement WM8962 DMIC supportMark Brown2011-04-26
| | | | | | | | | | | | DMIC support is automatically disabled when none of the GPIOs are set up to bring out the DMICCLK and DMICDAT pins at startup. Note that there's no support for controlling DMIC routing except the power control so the board DAPM configuration will need to manage DMIC enable and disable if analogue mics (eg, a headset) also exist.

| * ASoC: codecs: wm8962: Fix register cache incoherencyLars-Peter Clausen2010-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The multi-component patch(commit f0fba2ad1) moved the allocation of the register cache from the driver to the ASoC core. Most drivers where adjusted to this, but the wm8962 driver still uses its own register cache for its private functions, while functions from the ASoC core use the generic cache. Thus we end up with two from each other incoherent caches, which can lead to undefined behaviour. This patch fixes the issue by changing the wm8962 driver to use the generic register cache in its private functions.

* | ASoC: Decouple DAPM from CODECsLiam Girdwood2010-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes. Core implementation is from Liam Girdwood <lrg@slimlogic.co.uk> with some minor core changes, codecs and machine driver conversions from Jarkko Nikula <jhnikula@gmail.com>.
