This patch adds the digital loopback/bypass support for twl4030 codec.

The digital loopback will let the digimic0 (routed in the TX1 capture path
inside of TWL4030) data to be routed back to the RX2 playback path
(I2S stereo). It can also route the analog capture date routed through the
TX1 back to RX2.

Effectively the digital loopback is routing the audio from the TX1 capture path
to the RX2 playback path.

Move the WM8731 driver to use a more standard device registration
scheme where the device can be registered independantly of the ASoC
probe.

As a transition measure push the current manual code for registering
the WM8731 into the individual machine driver probes. This allows
separate patches to update the relevant architecture files with less
risk of merge issues.

This is a bit more idiomatic and makes identifying a configuration

Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

We have software control of the MCLK for the WM8731 so save a bit of
power by actively managing it within the machine driver, enabling it
only while the codec is active.

Once ASoC supports multiple boards and doesn't require the soc-audio
device the initial clock setup should be pushed down into the arch/arm
code but for now this reduces merge issues.

WM8753 uses a tricky way to switch DAIs "on the fly", for that it
registers 2 dummy DAIs and substitutes them depending on mixer control.

List element of registered dummy DAIs should be preserved to allow

Fix for the error when the audio module is unloaded.  On unregistering
the platform_device, platform_device_release will free the platform
data.If platform data is static the kernel panics when it is freed.
Instead use the platform device helper function to add data.

This change has been tested on DM644x EVM, DM644x SFFSDR and DM355 EVM.

Merge branch 'for-2.6.30' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6 into topic/asoc

ASoC supports both explicit codec drivers for AC97 devices and a simple
driver which uses the standard ALSA AC97 framework for codec support.
When used with the generic AC97 codec support that will provide the
ad hoc AC97 device for drivers like touchscreens to attach to so the
core shouldn't do so.

Update the CS4270 codec driver to allow applications to use the mixer to
control Digital Loopback, Soft Ramp, Zero Cross, Popguard, and Auto-Mute.
Soft Ramp, Zero Cross, and Auto-Mute are disabled by the driver when it first
initializes the hardware, but these features either don't work or interfere
with normal ALSA behavior.  However, they can now be re-enabled by an
application if desired.

Remove CONFIG_SND_SOC_CS4270_HWMUTE and always allow ASoC to control the mute
bits.  The driver previously and erroneously assumed that these bits
control only external muting circuitry, but they also control internal
muting circuitry, so they should always be used.

Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

This is a minor fix but helps to define dB ranges for volume controls.

Only DAC digital volume has full register value range from 0 to 127 but
ADC PGA gain and output stage volume controls don't.

For ADC PGA, maximum value is 119 and then it saturates to the same
gain value of 59.5 dB. For output stages, value 117 corresponds to -78.3 dB
and is muted for values 118 and above.

This machine driver enables sound functions on Mitac mio
a701 smartphone. Build upon ASoC v1, it handles :
 - rear speaker
 - front speaker
 - microphone
 - GSM

A global "Mio Mode" switch is not yet provided to cope with
audio path setup. As balance on audio chip line is no more
assured, an incorrect setup can produce a lot of heat and
even fry the battery behind the wm9713 and the speaker
amplifier.

It doesn't cope with :
 - headset jack
 - mio master mode
 - master volume control

This driver is backported from ASoc v2, and amputated from
scenario setups and master volume control.

In the Freescale MPC8610 sound drivers, relocate all code from the _prepare
functions into the corresponding _hw_params functions.  These drivers assumed
that the sample size is known in the _prepare function and not in the
_hw_params function, but this is not true.

Move the code in fsl_dma_prepare() into fsl_dma_hw_param().  Create
fsl_ssi_hw_params() and move the code from fsl_ssi_prepare() into it.

Turn off snooping for DMA operations to/from I/O registers, since that's not
necessary.
