Renesas R-Car MIPI CSI-2
|
------------------------
|
|
The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
|
Renesas R-Car family of devices. It is used in conjunction with the
|
R-Car VIN module, which provides the video capture capabilities.
|
|
Mandatory properties
|
--------------------
|
- compatible: Must be one or more of the following
|
- "renesas,r8a7795-csi2" for the R8A7795 device.
|
- "renesas,r8a7796-csi2" for the R8A7796 device.
|
- "renesas,r8a77965-csi2" for the R8A77965 device.
|
- "renesas,r8a77970-csi2" for the R8A77970 device.
|
|
- reg: the register base and size for the device registers
|
- interrupts: the interrupt for the device
|
- clocks: reference to the parent clock
|
|
The device node shall contain two 'port' child nodes according to the
|
bindings defined in Documentation/devicetree/bindings/media/
|
video-interfaces.txt. port@0 shall connect to the CSI-2 source. port@1
|
shall connect to all the R-Car VIN modules that have a hardware
|
connection to the CSI-2 receiver.
|
|
- port@0- Video source (mandatory)
|
- endpoint@0 - sub-node describing the endpoint that is the video source
|
|
- port@1 - VIN instances (optional)
|
- One endpoint sub-node for every R-Car VIN instance which is connected
|
to the R-Car CSI-2 receiver.
