ARM: EXYNOS4: Add support for M-5MOLS camera on Nuri board
Browse files Browse the repository at this point in the history 
Add voltage regulator and platform data definition for M-5MOLS sensor
and MIPI-CSI receiver drivers. Add CAM power domain dependencies for
FIMC device and set up camera port A GPIO. Configure I2C0 bus timings.
