2021-01-22media: dt-bindings: Convert video-interfaces.txt properties to schemasRob Herring1-639/+1
Convert video-interfaces.txt to DT schema. As it contains a mixture of device level and endpoint properties, split it up into 2 schemas. Binding schemas will need to reference both the graph.yaml and video-interfaces.yaml schemas. The exact schema depends on how many ports and endpoints for the binding. A single port with a single endpoint looks similar to this: port: $ref: /schemas/graph.yaml#/$defs/port-base properties: endpoint: $ref: video-interfaces.yaml# unevaluatedProperties: false properties: bus-width: enum: [ 8, 10, 12, 16 ] pclk-sample: true hsync-active: true vsync-active: true required: - bus-width additionalProperties: false Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Jacopo Mondi <jacopo@jmondi.org> Acked-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2018-10-04media: dt-bindings: media: Specify bus type for MIPI D-PHY, others, explicitlySakari Ailus1-1/+3
Allow specifying the bus type explicitly for MIPI D-PHY, parallel and Bt.656 busses. This is useful for devices that can make use of different bus types. There are CSI-2 transmitters and receivers but the PHY selection needs to be made between C-PHY and D-PHY; many devices also support parallel and Bt.656 interfaces but the means to pass that information to software wasn't there. Autodetection (value 0) is removed as an option as the property could be simply omitted in that case.

Add 'data-enable-active' property to endpoint node properties list. The property allows to specify the polarity of the data-enable signal, which when in active state determinates when data lines have to sampled for valid pixel data.

2018-06-28media: dt-bindings: media: Define "rotation" property for sensorsSakari Ailus1-0/+4
Sensors are occasionally mounted upside down to systems such as mobile phones or tablets. In order to use such a sensor without having to turn every image upside down, most camera sensors support reversing the readout order by setting both horizontal and vertical flipping. This patch documents the "rotation" property for camera sensors, mirroring what is defined for displays in Documentation/devicetree/bindings/display/panel/panel.txt .

2017-07-19media: dt: bindings: Explicitly specify bus typeSakari Ailus1-0/+5
In the vast majority of cases the bus type is known to the driver(s) since a receiver or transmitter can only support a single one. There are cases however where different options are possible, or the bus type cannot be automatically detected. The existing V4L2 OF support tries to figure out the bus type and parse the bus parameters based on that. This does not scale too well as there are multiple serial busses that share common properties. Some hardware also supports multiple types of busses on the same interfaces.
