This patchset contains five patches which add support for ASoC sound
drivers on ST's SPEAr13XX platform. Details of the SPEAr13XX
platforms can be seen here:

The ARCH and PLATFORM specific code for SPEAr13XX are
already under review in Russell King's ARM mailing
list(Linux-kernel-version 2.6.38-rc4).

This patchset has been tested for linux-kernel-version 2.6.38-rc4 and
on ARM platform.

Please review the same and consider for mainline inclusion.

Changes in machine driver code since V3
1.Use of snd_soc_register_card() rather than using the soc-audio device.
Changes in codec code since V3:
1. use standard cache sync implementation i.e. snd_soc_cache_sync()
Changes in spear Kconfig and Makefile since V2:
1.giving all the the modules snd-soc- prefixes to their names
Changes in codec code since V2:
1. use SOC_DOUBLE for volume control
2. remove default configuration for codec .offer them as runtime controls.
3. restore the register cache in resume
changes in platform code since V1:
1. Spilt machine driver from platform driver.
2. Updated rate supported.
3. Moved clock specific part from "spear13xx_i2s_set_dai_sysclk".
function to platform code. This function is removed now.
4. Function "spear13xx_i2s_startup" removed.
5. Function "spear13xx_i2s_shutdown" removed.

Changes in codec code since V1:
1. Removed sta529 version number.
2. Removed "sta529_read_reg_cache".
3. Removed function "sta529_write_reg_cache".
4. Removed function "sta529_write".
5. Moved sta529.h file contents to sta529.c file.
6. Move clock specific part from "spear_sta_set_dai_sysclk".
function to platform code. This function is removed now.
7. Renamed function names from spear_sta_* to sta_*.
8. Modified probe() function to avoid rewriting default chip values to hardware.
