title: THine THP7312
maintainers:
- Paul Elder <paul.elder@@ideasonboard.com>
description:
The THP7312 is a standalone ISP controlled over i2c, and is capable of
various image processing and correction functions, including 3A control. It
can be connected to CMOS image sensors from various vendors, supporting both
MIPI CSI-2 and parallel interfaces. It can also output on either MIPI CSI-2
or parallel. The hardware is capable of transmitting and receiving MIPI
interlaved data strams with data types or multiple virtual channel
identifiers.
