This is broken... did you check for warnings?
This is actually fine, the parent node has a ranges property:
https://github.com/torvalds/linux/blob/eb7081409f94a9a8608593d0fb63a1aa3d6f95d8/arch/arm64/boot/dts/amlogic/meson-s4.dtsi#L93
The parent ranges do not change here anything. You cannot have a reg
without unit address and the tools report it. No need to use reviewers
for this...
Oh I see now, I simply looked at the reg property, not the unit address.
Sorry indeed it's wrong and DTC should complain.
Yu, you should probably update your DTC version.
