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.
Example:
csi20: csi2@fea80000 {
compatible = "renesas,r8a7796-csi2";
reg = <0 0xfea80000 0 0x10000>;
interrupts = <0 184 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cpg CPG_MOD 714>;
power-domains = <&sysc R8A7796_PD_ALWAYS_ON>;
resets = <&cpg 714>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
csi20_in: endpoint@0 {
reg = <0>;
clock-lanes = <0>;
data-lanes = <1>;
remote-endpoint = <&adv7482_txb>;
};
};
port@1 {
#address-cells = <1>;
#size-cells = <0>;
reg = <1>;
csi20vin0: endpoint@0 {
reg = <0>;
remote-endpoint = <&vin0csi20>;
};
csi20vin1: endpoint@1 {
reg = <1>;
remote-endpoint = <&vin1csi20>;
};
csi20vin2: endpoint@2 {
reg = <2>;
remote-endpoint = <&vin2csi20>;
};
csi20vin3: endpoint@3 {
reg = <3>;
remote-endpoint = <&vin3csi20>;
};
csi20vin4: endpoint@4 {
reg = <4>;
remote-endpoint = <&vin4csi20>;
};
csi20vin5: endpoint@5 {
reg = <5>;
remote-endpoint = <&vin5csi20>;
};
csi20vin6: endpoint@6 {
reg = <6>;
remote-endpoint = <&vin6csi20>;
};
csi20vin7: endpoint@7 {
reg = <7>;
remote-endpoint = <&vin7csi20>;
};
};
};
};
