Konrad, on updating (ranges = <0 0 0 0xffffffff>; --> ranges;)
we see the below warnings:
arch/arm64/boot/dts/qcom/ipq9574.dtsi:103.3-10: Warning (ranges_format):
/soc at 0:ranges: empty "ranges" property but its #address-cells (1)
differs from / (2)
arch/arm64/boot/dts/qcom/ipq9574.dtsi:103.3-10: Warning (ranges_format): 
/soc at 0:ranges: empty "ranges" property but its #size-cells (1) differs
from / (2)

Looks like, empty ranges property isn't supported if the parent and
child address spaces are non-identical.
Would you suggest to retain the ranges as such?
(ranges = <0 0 0 0xffffffff>;)

Thanks,
Devi Priya
