From ea8c64ace86647260ec4255f483e5844d62af2df Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Jan 2018 16:21:13 +0100 Subject: dma-mapping: move swiotlb arch helpers to a new header phys_to_dma, dma_to_phys and dma_capable are helpers published by architecture code for use of swiotlb and xen-swiotlb only. Drivers are not supposed to use these directly, but use the DMA API instead. Move these to a new asm/dma-direct.h helper, included by a linux/dma-direct.h wrapper that provides the default linear mapping unless the architecture wants to override it. In the MIPS case the existing dma-coherent.h is reused for now as untangling it will take a bit of work.
