As Peter mentioned, you should use the mux-ctrl binding. Maybe this should have a mux node here too. That helps if we ever have other child nodes on the UART. The unit address and reg property values should match. > + }; > + gmsl-deserializer@1 { > + compatible = "maxim,max9260"; > + reg = <0x9>; > + }; > + gmsl-deserializer@2 { > + compatible = "maxim,max9260"; > + reg = <0xa>; > + }; > + gmsl-deserializer@3 { > + compatible = "maxim,max9260"; > + reg = <0xb>; > + }; > + gmsl-deserializer@4 { > + compatible = "maxim,max9260"; > + reg = <0x4>; > + }; > + gmsl-deserializer@5 { > + compatible = "maxim,max9260"; > + reg = <0x5>; > + }; > +}; > + > &scif3 { > pinctrl-0 = <&scif3_pins>; > pinctrl-names = "default"; > -- > 2.7.4 > -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
