[PATCH v2 1/3] dt-bindings: media: Add Sony IMX681

[Sergey Lebedev]

The Sony IMX681 is a CMOS image sensor used as the user-facing camera on
several Microsoft Surface devices. It operates from analog 2.8 V, digital
1.05 V and interface 1.8 V supplies, is programmable over I2C, and outputs
10-bit Bayer data over a two-lane MIPI CSI-2 D-PHY interface.

+description:
+  The Sony IMX681 is a CMOS active pixel image sensor with a square pixel
+  array, used as the user-facing camera on several Microsoft Surface devices.
+  It operates from analog 2.8 V, digital 1.05 V and interface 1.8 V supplies,
+  is programmable over I2C, and outputs 10-bit Bayer data over a two-lane
+  MIPI CSI-2 D-PHY interface.
