Subject: provide more common DMA API functions V2
Date: Mon, 17 Aug 2015 09:06:51 +0200 [thread overview]
Message-ID: <1439795216-32189-1-git-send-email-hch@lst.de> (raw)
Since 2009 we have a nice asm-generic header implementing lots of DMA API
functions for architectures using struct dma_map_ops, but unfortunately
it's still missing a lot of APIs that all architectures still have to
duplicate.
This series consolidates the remaining functions, although we still
need arch opt outs for two of them as a few architectures have very
non-standard implementations.
Changes since V1:
- keep a modified comment about dma_alloc_noncoherent vs
dma_cache_sync in the ARM asm/dma-mapping.h
- keep the ARM dma_set_mask instances to deal with dmabounce
