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