This applies to a few locations below too. Adding them would convey that to the reader, but wouldn't change the schema validation. We'd have to use 'additionalProperties' instead and also add 'remote-endpoint' everywhere (and 'reg' sometimes). I prefer not doing all that, but if we want it just for purposes of documenting the usage, that's fine. > > bus-type: > > - description: The type of the data bus. > > oneOf: > > - const: 1 # CSI-2 C-PHY > > - const: 3 # CCP2 > > diff --git a/Documentation/devicetree/bindings/media/i2c/ov5647.yaml b/Documentation/devicetree/bindings/media/i2c/ov5647.yaml > > index 280c62afae13..3b1ea9da437a 100644 > > --- a/Documentation/devicetree/bindings/media/i2c/ov5647.yaml > > +++ b/Documentation/devicetree/bindings/media/i2c/ov5647.yaml > > @@ -31,27 +31,15 @@ properties: > > maxItems: 1 > > > > port: > > - type: object > > - description: |- > > - Should contain one endpoint sub-node used to model connection to the > > - video receiver according to the specification defined in > > - Documentation/devicetree/bindings/media/video-interfaces.txt. > > + $ref: /schemas/graph.yaml#/$defs/port-base > > > > properties: > > endpoint: > > - type: object > > + $ref: /schemas/media/video-interfaces.yaml# > > + unevaluatedProperties: false > > > > properties: > > - remote-endpoint: > > - description: |- > > - phandle to the video receiver input port. > > - > > - clock-noncontinuous: > > - type: boolean > > - description: |- > > - Set to true to allow MIPI CSI-2 non-continuous clock operations. > > - > > - additionalProperties: false > > + clock-noncontinuous: true > > > > additionalProperties: false > > > > diff --git a/Documentation/devicetree/bindings/media/i2c/ov8856.yaml b/Documentation/devicetree/bindings/media/i2c/ov8856.yaml > > index cde85553fd01..c29b057ae922 100644 > > --- a/Documentation/devicetree/bindings/media/i2c/ov8856.yaml > > +++ b/Documentation/devicetree/bindings/media/i2c/ov8856.yaml > > @@ -57,16 +57,13 @@ properties: > > active low. > > > > port: > > - type: object > > + $ref: /schemas/graph.yaml#/$defs/port-base > > additionalProperties: false > > - description: > > - A node containing an output port node with an endpoint definition > > - as documented in > > - Documentation/devicetree/bindings/media/video-interfaces.txt > > > > properties: > > endpoint: > > - type: object > > + $ref: /schemas/media/video-interfaces.yaml# > > + unevaluatedProperties: false > > > > properties: > > data-lanes: > > @@ -79,18 +76,13 @@ properties: > > - const: 4 > > > > link-frequencies: > > - $ref: /schemas/types.yaml#/definitions/uint64-array > > - description: > > - Allowed data bus frequencies. 360000000, 180000000 Hz or both > > - are supported by the driver. > > - > > + maxItems: 2 > > + items: > > + enum: [ 360000000, 180000000 ] > > This is a limitation of the driver, not the device.

Warning on that seems valuable to me, so I think we should keep it. If someone with a better driver complains, we can drop it. I can keep the description with 'Frequencies listed are driver, not h/w limitations'. Rob
