Subject: [PATCH v2 1/4] dt-bindings: media: i2c: Add OX05B1S sensor
Add bindings for Omnivision OX05B1S sensor.
Also add compatible for Omnivision OS08A20 sensor.
Signed-off-by: Mirela Rabulea <mirela.rabulea@....com>
---
Changes in v2:
Small updates on description
Update subject, drop "bindings" and "driver"
Just one binding patch (squash os08a20 bindings)
Re-flow to 80 columns.
Drop clock name (not needed in case of single clock)
Make the clock required property, strictly from sensor module point of view, it is mandatory (will use a fixed clock for nxp board)
Add regulators: avdd, dvdd, dovdd
Add $ref: /schemas/media/video-interface-devices.yaml
Drop assigned-clock* properties (defined in clocks.yaml)
Keep "additionalProperties : false" and orientation/rotation (unevaluatedProperties: false was suggested, but only orientation/rotation are needed from video-interface-devices.yaml)
Include assigned-clock* in the example, for completeness sake (although it was also suggested to omit them)
