A few more ASoC updates, the main one is the move of the audmux driver
from arch/arm into sound/soc. There's also some general driver specific
tweaks and fixes.
commit 891271c "ASoC: Convert wm8804 to direct regmap API usage"
only converts wm8804_spi_probe to use regmap_init_spi.
This patch adds missing regmap_init_i2c in wm8804_i2c_probe.

When we are out of system sleep always use audio mode for jack detection
in order to avoid potential performance issues handing off between modes.
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
of bugfixes and driver updates there's quite a few framework enhancements.
Most are either small or are laying the groundwork for user visible
features (especially dynamic PCM), the most directly visible change is
the dmaengine library. There's also a bunch of regmap API enhancements
pulled into the tree so that either the framework or drivers can take
advantage of the new features.
Changes include:
- Support for widgets not associated with a CODEC, an important part of
the dynamic PCM framework.
- A library factoring out the common code shared by dmaengine based DMA
drivers contributed by Lars-Peter Clausen. This will save a lot of
code and make it much easier to deploy enhancements to dmaengine.
- Support for binary controls, used for providing runtime configuration
of algorithm coefficients.
- A new DAPM widget type for regulator supplies allowing drivers for
devices that can power down unused supplies while active to do without
any per-driver code.
- DAPM widgets for DAIs, initially giving a speed boost for playback
startup and shutdown and also the basis for CODEC<->CODEC DAI link
support.
- Support for specifying the number of significant bits on audio
interfaces, useful for allowing applications to know how much effort to
put into generating data for a larger sample format.
- Conversion of the FSI driver used on some SH processors to DMAEngine.
- New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200.

Normally this will have no effect as we set detection up at system startup
before DAPM syncs take effect, this will only be useful if the system
enables and disables detection at runtime.

When an external capacitor is connected to MICBIAS2 on devices with
jack detection (which is not required but may be done in some systems)
then the loading may mean that better performance is obtained when
the microphone bias is enabled normally rather than using the low power
mode. Provide platform data allowing systems to indicate if they require
this.
