[Xen-devel] [PATCH 08/11] dts: arm64: layerscape: add dma-ranges property to pcie nodes

[Nicolas Saenz Julienne <nsaenzjulienne@xxxxxxx>]

The bus behind the board's PCIe core has DMA addressing limitations. Add
an empty 'dma-ranges' property on all PCIe bus descriptions to inform
the OF core that a translation is due further down the line.
