Message-ID <[email protected]>
The Sony IMX908 is an 8.39 megapixel (3856x2176) CMOS image sensor
with a MIPI CSI-2 output interface, supporting RAW10 and RAW12 output
over 2 or 4 data lanes.

Add device tree bindings for the sensor.

Changes in v2:
- Reword subject to drop the redundant "bindings" suffix.
- Reference video-interfaces.yaml for the endpoint and switch to
  unevaluatedProperties, fixing the remote-endpoint check.
- Drop "link-frequencies: true".
- MAINTAINERS: drop the L: line.
- MAINTAINERS: move the driver F: line to patch 2.

+description:
+  Sony IMX908 diagonal 6.42 mm (Type 1/2.8) CMOS active pixel type
+  solid-state image sensor with a square pixel array and 8.39 M
+  (3856x2176) pixels, supporting MIPI CSI-2 output with
+  RAW10 and RAW12 formats, configured as either 2 or 4 data lanes.
+  The I2C address is fixed to 0x1A as per sensor data sheet.
