The rp1.dtso overlay doesn't work on its own as there are additional settings needed as seen in bcm2712-rpi-5-b.dts. In addition, the 'rp1_nexus' node is applied to the wrong place in the DT as it should be under a PCIe root port rather than the host bridge. There's also a duplicate overlay in drivers/misc/rp1/. For these reasons, just drop the overlay to fix the warning until all these issues can be fixed. Signed-off-by: Rob Herring (Arm) Reviewed-by: Andrea della Porta --- The missing applying of rp1.dtbo is now a warning in v6.19-rc1. This should be sent to Linus ASAP. v2: - Drop the overlay instead of trying to rework. The addition of ethernet0 alias complicates that. --- arch/arm64/boot/dts/broadcom/Makefile | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/broadcom/Makefile b/arch/arm64/boot/dts/br= oadcom/Makefile index 83d45afc6588..031875a277d7 100644 --- a/arch/arm64/boot/dts/broadcom/Makefile +++ b/arch/arm64/boot/dts/broadcom/Makefile @@ -14,8 +14,7 @@ dtb-$(CONFIG_ARCH_BCM2835) +=3D bcm2711-rpi-400.dtb \ bcm2837-rpi-3-b.dtb \ bcm2837-rpi-3-b-plus.dtb \ bcm2837-rpi-cm3-io3.dtb \ - bcm2837-rpi-zero-2-w.dtb \ - rp1.dtbo + bcm2837-rpi-zero-2-w.dtb =20 subdir-y +=3D bcmbca subdir-y +=3D northstar2 --=20 2.51.0
