13description: |
14  The eXtended Image Sensor Controller (XISC) device provides the video input capabilities for the
15  Microchip AT91 SAM family of devices.
16
17  The XISC has a single internal parallel input that supports RAW Bayer, RGB or YUV video.
18  The source can be either a demuxer from a CSI2 type of bus, or a simple direct bridge to a
19  parallel sensor.
20
21  The XISC provides one clock output that is used to clock the demuxer/bridge.

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