| 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. |
