This line is wrong since the child nodes themselves are optional in i2c-gate.txt (and i2c-mux.txt). I guess you can just drop it since the child nodes are mentioned in i2c-gate.txt (and i2c-mux.txt).

+ fpc0i2c0: i2c@0 {...change i2c@0 to i2c-gate...
+ #address-cells = <1>; + #size-cells = <0>; + reg = <0>;
...and drop reg. Cheers, Peter
