I will admit I know next to nothing about PCI techically, so I can't even comment with confidence that this is needed there, but it looks similar to other descriptions modified in this patch series. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/qcom/sa8540p.dtsi#n197 Thanks, Andrew
