mfd: Don't suspend WM8994 if the CODEC is not suspended

2011-03-02T09:57:50+00:00

ASoC supports keeping the audio subsysetm active over suspend in order
to support use cases such as audio passthrough from a cellular modem
with the main CPU suspended. Ensure that we don't power down the CODEC
when this is happening by checking to see if VMID is up and skipping
suspend and resume when it is. If the CODEC has suspended then it'll
turn VMID off before the core suspend() gets called.

ASoC: Allow user-specified WM8958 multiband compressor configurations

2010-12-01T11:47:29+00:00

The paramters of the WM8958 multiband compressor can be tuned by the
user for their system using a graphical configuration tool on the host.
Allow the user to specify a set of such paramters in platform data and
select between them at runtime.

ASoC: Add WM8958 microphone detection support

2010-11-27T10:32:13+00:00

The WM8958 contains an advanced accessory detection feature which allows
detection of up to seven different impedence levels on the microphone
bias output, including detection of video outputs. Since some of the
more involved accessory interfaces may involve noticable interactions
with external components a simple detection scheme is provided by
default with the option to provide custom handling of accessory detect.

ASoC: Add WM8958 Multi-band compressor support

2010-11-27T10:32:13+00:00

The WM8958 features a multi-band compressor which can be enabled on
any of the AIF inputs. The MBC allows different gains to be applied to
differnt audio bands, providing an improvement in perceived loudness
of the signal by avoiding overdriving the output transducers. This
patch enables support for the MBC.

mfd: Add initial WM8958 support

2010-11-26T15:16:19+00:00

The WM8958 is a derivative of the WM8994 which is register compatible
with the addition of some extra features, mostly in the CODEC side.
The major change visible at the MFD level is that rather than a single
DBVDD supply we now have three separate DBVDDs so we must request and
enable a different set of supplies.
