IIRC some dtsi files already exist. Perhaps there could be a bcm283x-rpi-smsc9512.dtsi and bcm283x-rpi-smsc9514.dtsi, and even a bcm283x-rpi-smsc-eth.dtsi since 99% of those two are common? Hopefully that doesn't sound like busy work/bike-shedding too much. > diff --git a/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts b/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts > +&usb { > + usb1@1 { > + compatible = "usb0424,9514"; > + reg = <01>; Here and ... > + #address-cells = <1>; > + #size-cells = <0>; > + > + ethernet: usbether@1 { > + compatible = "usb0424,ec00"; > + reg = <01>; ... here, reg should be "1" not "01".

On my systems, I have: RPi B (original, rev 1, 2 USB ports): 9512 RPi B (rev 2 w/ P5, 2 USB ports): 9512 RPi B+ (4 USB ports): 9514 RPi 2 (4 USB ports): 9514 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
