[U-Boot] [PATCH 0/7 V3] EXYNOS5: Add audio support for Snow

[U-Boot] [PATCH 0/7 V3] EXYNOS5: Add audio support for Snow

[Rajeshwari Shinde]

This patch set creats a new configuration file and DTS file for Snow.
Driver for MAX98095 is added and support for same is incorporated in
sound driver and Snow Board.
This patchset is based on top of 
"[U-Boot] [PATCH 0/2 V2] SMDK5250: Set Initial PMIC Values"

Changes in V2:
        - Corrected multi-line comment style
Changes in V3:
	- Removed non DT support for MAX98095
	- Config for both MAX98095 and WM8994 added in
	exynos5 config file.

Rajeshwari Shinde (7):
  EXYNOS5: Add function to enable XXTI clock source
  Sound: MAX98095: Add the driver for codec
  Sound: Support for MAX98095 codec in driver
  EXYNOS5: GPIO to enable MAX98095
  EXYNOS5: FDT: Add compatible strings for MAX98095
  EXYNOS5: Add initial DTS file for Snow.
  EXYNOS5: Snow: Add a configuration file

Somewhat unrelated to this patch: Assuming I am correct in thinking
that the kernel uses maxim,max77686-pmic instead of
maxim,max77686_pmic, can you please prepare a patch at some point to
move U-Boot over to using the same compatible string?

Regards,
Simon
