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.

This property is for lane reordering between the THP7312 and the

If this property is omitted four-lane operation is assumed. For

two-lane operation the property must be set to <1 2>.
