+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.
