+description:
+  The eXtended Image Sensor Controller (XISC) device provides the video input capabilities for the
+  Microchip AT91 SAM family of devices.
+
+  The XISC has a single internal parallel input that supports RAW Bayer, RGB or YUV video.
+  The source can be either a demuxer from a CSI2 type of bus, or a simple direct bridge to a
+  parallel sensor.
+
+  The XISC provides one clock output that is used to clock the demuxer/bridge.
