Renesas R-Car MIPI CSI-2
------------------------
The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
Renesas R-Car and RZ/G2 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,r8a774a1-csi2" for the R8A774A1 device.
- "renesas,r8a774b1-csi2" for the R8A774B1 device.
- "renesas,r8a774c0-csi2" for the R8A774C0 device.
- "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.
- "renesas,r8a77980-csi2" for the R8A77980 device.
- "renesas,r8a77990-csi2" for the R8A77990 device.
- reg: the register base and size for the device registers
- interrupts: the interrupt for the device
- clocks: A phandle + clock specifier for the module clock
- resets: A phandle + reset specifier for the module reset
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.
