Simple utility layer for creating ASoC machine instances based on data
in the OpenFirmware device tree.  OF aware platform drivers and codec
drivers register themselves with this framework and the framework
automatically instantiates a machine driver.  At the moment, the driver
is not very capable and it is expected to be extended as more features
are needed for specifying the configuration in the device tree.

This is most likely temporary glue code to work around limitations in
the ASoC v1 framework.  When v2 is merged, most of this driver will
need to be reworked.

Most of the ASoC controls refer to the maximum value that can be set for
a control as mask but there is no actual requirement for all bits to be
set at the highest possible value making the name mask misleading.
Change the code to use max instead.

Some codecs have unusual features in their register maps such as very
large registers representing arrays of coefficients. Support these
codecs in the register cache sysfs file by allowing them to provide a
function register_display() overriding the default output for register
contents.

Also ensure that we don't overflow PAGE_SIZE while writing out the
register dump.

The error path in cs4270_probe/cs4270_remove is pretty broken:
* If cs4270_probe fails, codec is leaked.
* If snd_soc_register_card fails, cs4270_i2c_driver stays registered.
* If I2C support is enabled but no I2C device is found, i2c_del_driver
  is never called (neither in cs4270_probe nor in cs4270_remove.

Fix all 3 problems by implementing a clean error path in cs4270_probe
and jumping to its labels as needed.

Update the CS4270 ALSA device driver to use the new-style I2C interface.
Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the
device trees can no longer be probed by old-style I2C drivers.  The device
tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since
2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem.
Since that's no longer the case, the best solution is to update the CS4270
driver to a new-style interface, rather than try to revert the behavior of
new PowerPC I2C subsystem.

Many SoC audio codec drivers have improper freeing of memory in error
paths.

* codec is allocated in the platform device probe function, but is not
  freed there in case of error. Instead it is freed in the i2c device
  probe function's error path. However the success or failure of both
  functions is not linked, so this could result in a double free (if
  the platform device is successfully probed, the i2c device probing
  fails and then the platform driver is unregistered.)

* codec->private_data is allocated in many platform device probe
  functions but not freed in their error paths.

This patch hopefully solves all these problems.

If an OSS application calls SNDCTL_DSP_SYNC, then ALSA will call the driver's
_hw_params and _prepare functions again.  On the Freescale MPC8610 DMA ASoC
driver, this caused the DMA controller to be unneccessarily re-programmed, and
apparently it doesn't like that.  The DMA will then not operate when
instructed.  This patch relocates much of the DMA programming to
fsl_dma_open(), which is called only once.

The Freescale MPC8610 SSI device has the option of using one clock for both
transmit and receive (synchronous mode), or independent clocks (asynchronous).
The SSI driver, however, programs the SSI into synchronous mode and then
tries to program the clock registers independently.  The result is that the wrong
sample size is usually generated during recording.

This patch fixes the discrepancy by restricting the sample rate and sample size
of the playback and capture streams.  The SSI driver remembers which stream
is opened first.  When a second stream is opened, that stream is constrained
to the same sample rate and size as the first stream.

A future version of this driver will lift the sample size restriction.
Supporting independent sample rates is more difficult, because only certain
codecs provide dual independent clocks.
