+title: Microchip eXtended Image Sensor Controller (XISC)
+
+maintainers:
+ - Eugen Hristev <eugen.hristev@microchip.com>
+
+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.

+ description:
+ As the XISC is usually connected to a demux/bridge, the XISC receives
+ the same type of input, however, it should be aware of the type of
+ signals received. The mipi-mode enables different internal handling
+ of the data and clock lines.
