Rather than trying to work around machine drivers which try to reprogram
the FLL while it is providing SYSCLK just return an error if they try.
This will avoid audio glitches during FLL reconfiguration, or at least
move the introduction of the glitches to the machine driver.
Since disabling the source for an active SYSCLK is not supported in the
first place systems shouldn't be doing this in the first place.

ML26124-01HB/ML26124-02GD is 16bit monaural audio CODEC which has high
resistance to voltage noise. On chip regulator realizes power supply rejection
ratio be over 90dB so more than 50dB is improved than ever. ML26124-01HB/
ML26124-02GD can deliver stable audio performance without being affected by noise
from the power supply circuit and peripheral components. The chip also includes
a composite video signal output, which can be applied to various portable device
requirements. The ML26124 is realized these functions into very small package
the size is only 2.56mm x 2.46mm therefore can be construct high quality sound
system easily.
ML26124-01HB is 25pin WCSP package; ML26124-02GD is 32pin WQFN package.

This change adds the logic to support using the jack detect mechanism built
in to the codec to detect both when a jack was inserted and what type of
jack is present.
This change also supports the use of an external mechanism for headphone
detection. If this mechanism exists, when the max98095_jack_detect function
is called, the hp_jack is simply passed NULL.
This change supports both simple headphones, powered headphones, microphones
and headsets with both headphones and a mic.

DAPM now has a DAPM-level lock which it manages itself so we don't need
to take the CODEC mutex to call DAPM any more. Also remove a redundant
call to snd_soc_dapm_sync(), jack reporting also triggers a DAPM sync.

It's more idiomatic to do this and it means we don't try to bring up the

Last minute ASoC updates for 3.4
There's a couple of small features here that were added late on but have

house between the two solutions that the latest change allows the

The optimal management of VMID depends on a number of factors which vary
dynamically at runtime, for example the connection to a system docking
station. In some circumstances it is desirable to keep VMID enabled all
the time, in others it is desirable to aggressively power it up and down.
Provide a callback allowing machine driver to configure either the normal
power up/down mode (WM8994_VMID_MODE_NORMAL) or to maintain VMID even
when idle (WM8994_VMID_MODE_FORCE). This callback, wm8994_vmid_mode(),
should be called with the CODEC lock.

Currently we can the accdet mutex from within DAPM when updating the device
state which means we take accdet then the CODEC mutex but we also do the
locking the other way around when responding to the jackdet IRQ. Move all
the jackdet use of the CODEC mutex out of the accdet lock to avoid this.
Since all the DAPM interactions depend only on a single threaded IRQ this
is still serialised.
The locking improvements in 3.5 allow a better solution there.

of bugfixes and driver updates there's quite a few framework enhancements.
Most are either small or are laying the groundwork for user visible

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 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
