4.5 Camera interface

SIMT1502 contains two camera interface. Primary camera interface use 2-lane MIPI_CSI0,
supports CMOS and CCD sensors, up to 8MP sensors. Secondary camera interface use 1-lane
MIPI_CSI1, and 1.5Gbps per lane. Both are controlled by I2C bus.
See Table4-5 and Figure4-3for more details.
