I agree that the warning should be silenced however I have a feeling = this might need to be tested. The VIN bindings assigns special meaning = to which port reg an endpoint is described in and handles each of them = differently, see the biding documentation. As the single port described here is port 0 I think removing the reg = property will probably work but is it correct? If someone with a Draak = board could test this patch it would be great! > = > This addresses the following warning: > = > # make dtbs W=3D1 > ... > arch/arm64/boot/dts/renesas/r8a77995-draak.dts:492.8-503.4: Warning (gra= ph_child_address): /soc/video@e6ef4000/ports: graph node has single child n= ode 'port@0', #address-cells/#size-cells are not necessary > = > Fixes: 6a0942c20f5c ("arm64: dts: renesas: draak: Describe CVBS input") > Cc: Jacopo Mondi > Signed-off-by: Simon Horman > --- > arch/arm64/boot/dts/renesas/r8a77995-draak.dts | 7 +------ > 1 file changed, 1 insertion(+), 6 deletions(-) > = > Developed on top of renesas-devel-20190308-v5.0 > Compile tested only > = > diff --git a/arch/arm64/boot/dts/renesas/r8a77995-draak.dts b/arch/arm64/= boot/dts/renesas/r8a77995-draak.dts > index 244b0dda03ed..8fba6cde5905 100644 > --- a/arch/arm64/boot/dts/renesas/r8a77995-draak.dts > +++ b/arch/arm64/boot/dts/renesas/r8a77995-draak.dts > @@ -490,12 +490,7 @@ > status =3D "okay"; > = > ports { > - #address-cells =3D <1>; > - #size-cells =3D <0>; > - > - port@0 { > - reg =3D <0>; > - > + port { > vin4_in: endpoint { > remote-endpoint =3D <&adv7180_out>; > }; > -- = > 2.11.0 > = -- = Regards, Niklas S=F6derlund _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
