+* Maxim Integrated MAX9286 GMSL Quad 1.5Gbps GMSL Deserializer
+
+Required Properties:
+ - compatible: Shall be "maxim,max9286"
+
+The following required properties are defined externally in
+Documentation/devicetree/bindings/i2c/i2c-mux.txt:
+ - Standard I2C mux properties.
+ - I2C child bus nodes.
+
+A maximum of 4 I2C child nodes can be specified on the MAX9286, to
+correspond with a maximum of 4 input devices.
+
+The device node must contain one 'port' child node per device input and output
+port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
+are numbered as follows.
+
+ Port Type
+ ----------------------
+ 0 sink
+ 1 sink
+ 2 sink
+ 3 sink
+ 4 source
+
+Example:
+&i2c4 {
+ gmsl-deserializer@0 {
Not @4c?
+ compatible = "maxim,max9286";
+ reg = <0x4c>;
+ poc-supply = <&poc_12v>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
[...]
+ i2c@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ camera@51 {
+ compatible = MAXIM_CAMERA0;
What, again?
+ reg = <0x51 0x61>;
+
+ port {
+ rdacm20_out0: endpoint {
+ remote-endpoint = <&max9286_in0>;
+ };
+ };
+ };
+ };
+ };
+};
