maintainers:

description:
The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656)
video data busses. The I2C bus is the main control bus and additionally the
SPI bus is used, mostly for transferring the firmware to and from the
device. Two slave device nodes corresponding to these control bus
interfaces are required and should be placed under respective bus
controller nodes.
