13description: |
14  The Image Sensor Controller (ISC) device provides the video input capabilities for the
15  Atmel/Microchip AT91 SAMA family of devices.
16
17  The ISC has a single parallel input that supports RAW Bayer, RGB or YUV video,
18  with both external synchronization and BT.656 synchronization for the latter.
