we tried to fix as much as possible in the past. So there are only those
left, which i don't know how to fix it properly (and without breaking
things):

arch/arm/boot/dts/bcm283x.dtsi:54.6-651.4: Warning
(unit_address_vs_reg): /soc: node has a reg or ranges property, but no
unit name

This from the SoC specific dtsi files which add values for the ranges /
dma-ranges.

soc {
ÂÂÂ ÂÂÂ ranges = <0x7e000000 0x20000000 0x02000000>;
ÂÂÂ ÂÂÂ dma-ranges = <0x40000000 0x00000000 0x20000000>;
};

arch/arm/boot/dts/bcm283x.dtsi:648.12-650.5: Warning (simple_bus_reg):
/soc/gpu: missing or empty reg/ranges property

This comes from the following simple bus child node:

vc4: gpu {
ÂÂÂ ÂÂÂ ÂÂÂ compatible = "brcm,bcm2835-vc4";
};

This issue should also exists in bcm-cygnus.dtsi. From the hardware side
the GPU is part of the SoC, but maybe we should move this node out of
the SoC simple bus?
