+// DMA Framework - Client API definition.

+// Inline implementations of functions which (originally) exposed DMA HAI
+// details that are now, after the header file split into dma_v2.h and
+// dma_hai.h, no longer meant to be visible to DMA clients. This file is only
+// included for DMA_APIV2 clients.
+//
+// This file is not meant to be a permanent one, and may eventually be removed
+// together with the deprecated functions it implements.
