1Renesas R-Car MIPI CSI-2
2------------------------
3
4The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
5Renesas R-Car and RZ/G2 family of devices. It is used in conjunction with the
6R-Car VIN module, which provides the video capture capabilities.
7
8Mandatory properties
9--------------------
10 - compatible: Must be one or more of the following
11 - "renesas,r8a774a1-csi2" for the R8A774A1 device.
12 - "renesas,r8a774c0-csi2" for the R8A774C0 device.
13 - "renesas,r8a7795-csi2" for the R8A7795 device.
14 - "renesas,r8a7796-csi2" for the R8A7796 device.
15 - "renesas,r8a77965-csi2" for the R8A77965 device.
16 - "renesas,r8a77970-csi2" for the R8A77970 device.
17 - "renesas,r8a77980-csi2" for the R8A77980 device.
18 - "renesas,r8a77990-csi2" for the R8A77990 device.
19
20 - reg: the register base and size for the device registers
21 - interrupts: the interrupt for the device
22 - clocks: A phandle + clock specifier for the module clock
23 - resets: A phandle + reset specifier for the module reset
24
25The device node shall contain two 'port' child nodes according to the
26bindings defined in Documentation/devicetree/bindings/media/
27video-interfaces.txt. port@0 shall connect to the CSI-2 source. port@1
28shall connect to all the R-Car VIN modules that have a hardware
29connection to the CSI-2 receiver.
30
31- port@0- Video source (mandatory)
32 - endpoint@0 - sub-node describing the endpoint that is the video source
33
34- port@1 - VIN instances (optional)
35 - One endpoint sub-node for every R-Car VIN instance which is connected
36 to the R-Car CSI-2 receiver.
