This gave the wrong result (matching the root node instead of the motherboard node), so broke the clocks and some other devices for VExpress boards. = Move the whole node back into its original position. This re-introduces the dtc warning, but is conceptually the right thing to do. The dtc warning seems to be overzealous here, there are discussions on fixing or relaxing this check instead. = Link: https://lore.kernel.org/r/20200603162237.16319-1-andre.przywara@a= rm.com Fixes: d9258898ad49 ("arm64: dts: vexpress: Move fixed devices out of b= us node") Reported-and-tested-by: Guenter Roeck Signed-off-by: Andre Przywara Signed-off-by: Sudeep Holla diff --git a/arch/arm/boot/dts/vexpress-v2m-rs1.dtsi b/arch/arm/boot/dts/ve= xpress-v2m-rs1.dtsi index e6308fb76183..a88ee5294d35 100644 --- a/arch/arm/boot/dts/vexpress-v2m-rs1.dtsi +++ b/arch/arm/boot/dts/vexpress-v2m-rs1.dtsi @@ -100,79 +100,6 @@ };
