[PATCH 1/2] dt-bindings: media: i2c: Add Sony IMX662 sensor

[Alexander Shiyan <eagle.alexander923@gmail.com>]

Add device tree binding documentation for the Sony IMX662 CMOS image
sensor. The sensor features a native pixel array of 1936x1100
(effective 1920x1080) and supports MIPI CSI-2 output with 2 or 4 data
lanes, RAW10/RAW12 formats, and both colour and monochrome variants.
The link-frequencies property accepts up to eight values corresponding
to the allowed MIPI data rates.

+
+description:
+  The Sony IMX662 is a 1/2.8-inch CMOS image sensor with a pixel
+  array of 1936x1100 pixels, capable of 1920x1080 resolution at up
+  to 90 fps. It supports MIPI CSI-2 output with 2 or 4 data lanes,
+  RAW10/RAW12 output, and both colour and monochrome variants.
