[PATCH V2 00/10]

[Dong Aisheng]

This patch series is to add audio support based on saif for mxs platform.
The driver only supports playback currently.
For capturing, due to hardware limitation that we have to use two saif
instances to implement full duplex (playback & recording), we need to
figure out a good design to fit in ASoC as the following work.

In addition, we simply just support master mode since saif tx can
only work as a master due to hw limitation(rx can work in both
master & slave mode).

Code is written based on the branch imx-for-3.1 in sascha's tree
http://git.pengutronix.de/git/imx/linux-2.6.git

Tested on MX28EVK.

Main changes since v1:
 * export saif mclk control interface to machine driver.
   Machine driver can decide whether it needs to use mclk supplied by
   saif according to its requirement.
 * error checking improvement
 * remove a few unneccesary code
