Zhen Lei 8ed74a0122 arm64: dts: broadcom: clear the warnings caused by empty dma-ranges ... [ Upstream commit 2013a4b684 ] The scripts/dtc/checks.c requires that the node have empty "dma-ranges" property must have the same "#address-cells" and "#size-cells" values as the parent node. Otherwise, the following warnings is reported: arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning \ (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but \ its #address-cells (1) differs from / (2) arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning \ (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but \ its #size-cells (1) differs from / (2) Arnd Bergmann figured out why it's necessary: Also note that the #address-cells=<1> means that any device under this bus is assumed to only support 32-bit addressing, and DMA will have to go through a slow swiotlb in the absence of an IOMMU.
