What do you suggest i change it into? > I took the example from original dtsi file: > arch/arm/boot/dts/broadcom/bcm283x.dtsi s/uart1: // The "uart1" part is a label. The dtsi needs it so that the &uart1 syntax can be used from a dts file to set properties etc, but that's no required in bindings where there are no references to the node, so we remove them.
