Inderpal Singh
inderpal.singh at linaro.org
Mon Aug 22 02:39:23 EDT 2011
From: Inderpal Singh <inderpal.s at samsung.com>
Configure MAX8997 PMIC and provide platform specific data
for origen.
Signed-off-by: Inderpal Singh <inderpal.singh at linaro.org>

Changes from v1:
- Removed soc-audio
- Used macro for GPIO pin
- irq assigned statically
- Rectified mismatches in constraints flags
- Removed assigning of array index
