+description: |-
+  The AP1302 is a standalone ISP for ON Semiconductor sensors. It interfaces to
+  up to two RAW CMOS sensors over MIPI CSI-2 connections, processes the two
+  video streams and outputs YUV frames to the host over a MIPI CSI-2 interface.
+  Frames are output side by side or on two virtual channels.
+
+  The sensors must be identical. They are connected to the AP1302 on dedicated
+  I2C buses, and are controlled by the AP1302 firmware. They are not accessible
+  from the host.
