[PATCH 4/4] ARM: S5PV210: UNIVERSAL_C210: Add support for M-5MOLS image sensor
Sylwester Nawrocki
s.nawrocki at samsung.com
Fri Sep 16 06:27:53 EDT 2011
Add voltage regulator definitions for M-5MOLS camera, platform data
definition for the sensor and MIPI-CSI receiver drivers.
Add CAM power domain dependencies for FIMC and CSIS devices.
Define required I2C0 bus timings. Setup camera port A GPIO.
