Ajay Kumar - Dec. 13, 2012, 11:29 a.m.
Add panel_info structure required by LCD driver
and DP panel platdata for SMDK5250.
Add GPIO configuration for LCD.
Enable FIMD and DP support on SMDK5250.
DP Panel size: 2560x1600.
We use 16BPP resolution to get LCD console.

why don't you use cfg_gpio in panel_info structure?
