+* Juniper I2C Mux on I2CS
+
+ I2C mux driver for switching the RE access to the FPC i2c bus.
+ Compatible with the FPC variant of the I2CS.
+
+Required properties:
+
+ - compatible: "jnx,i2cs-mux-i2cs".
+
+The following required properties are defined externally:
+
+ - Standard I2C mux properties. See i2c-mux.txt in this directory.
+ - I2C child bus nodes. See i2c-mux.txt in this directory.
+
+Example:
+
+fpc0_mux {
+ compatible = "jnx,i2c-mux-i2cs";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ fpc0i2c0: i2c@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+ };
+};
