This series moves the DT 'dma-ranges' parsing into common helpers utilizing a resource list. There's no (intended) functional change in this series though I'm also working on a separate series now in dt/next to improve the handling of 'dma-ranges' and dma masks. The last patch may need to wait if there's any new users of devm_of_pci_get_host_bridge_resources. Only versatile has been tested (on QEMU). The rest is compiled only. A git branch is here[1].
