+description:
+  The Sony IMX728 is a 1/1.72-Inch CMOS Solid-state image sensor with a
+  color square pixel array and 8.39M active pixels. It is programmed
+  through an I2C interface.
+
+  The sensor can output up to 3840x2160 at a maximum of 45 frames/s over
+  a CSI-2 serial interface. It supports RAW24/20/16/12 and 10.
