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.
