v8->v9:
- Make link-frequencies required

v7->v8:
- Add Conor's tag

v5->v6:
- sashiko: use 'unevaluatedProperties: false' at the top level to allow
  properties from video-interface-devices.yaml

v4->v5:
- reflow description to 80 cols and drop |-
- remove 'reg' description
- remove 'anyOf' from data-lanes
- remove 'link-frequencies' from required properties
- remove 'clock-continuous: true' as we already allow all properties
  from 'video-interfaces.yaml'
- remove tabs from the example

+description:
+  2.2 MP NIR enhanced global shutter image sensor designed for 2D and 3D
+  consumer and industrial machine vision applications. Due to its small size,
+  configurability and high sensitivity both in visual as well as NIR, the
+  Mira220 is well suited for 2D and 3D applications, which include Active Stereo
+  Vision, Structured Light Vision for Robotics and AR/VR.
