Nope:

../arch/arm64/boot/dts/amlogic/meson-s4.dtsi:105.35-127.6: Warning
(unit_address_vs_reg): /soc/apb4@...00000/clock-controller: node has a
reg or ranges property, but no unit name

Test your patches better before using reviewers time for trivial
compile-time fixes. The same rules for C code apply for DTS.
