Subject: [PATCH v3 4/8] dt-bindings: PCI: qcom-ep: consolidate DMA vs
non-DMA usecases
On Qualcomm platforms here are two major kinds of PCIe EP controllers:
ones which use eDMA and IOMMU and the ones which do not (like SDX55 /
SDX65). It doesn't make sense to c&p similar properties all over the
place. Merge these two usecases into a single conditional clause.
