+title: Atmel Image Sensor Controller (ISC)

+  - Eugen Hristev <eugen.hristev@microchip.com>
+
+description: |
+  The Image Sensor Controller (ISC) device provides the video input capabilities for the
+  Atmel/Microchip AT91 SAMA family of devices.
+
+  The ISC has a single parallel input that supports RAW Bayer, RGB or YUV video,
+  with both external synchronization and BT.656 synchronization for the latter.
