+description: |-
+  The ADDI9036 is a complete, 45 MHz, front-end solution for charge coupled
+  device (CCD) time of flight (TOF) imaging applications. It is programmable
+  through I2C interface. Image data is sent through MIPI CSI-2 2 lanes and
+  can output two RAW12 packed data streams. One is IR and the other is Depth.
+  Each data stream is on a separate or same MIPI Virtual Channel, depending
+  on configuration and each have 640x480 resolution.
