| H A D | dma-mapping.c | 6ecba8eb Fri Apr 25 09:31:45 CDT 2014 Catalin Marinas <catalin.marinas@arm.com> arm64: Use bus notifiers to set per-device coherent DMA ops
Recently, the default DMA ops have been changed to non-coherent for
alignment with 32-bit ARM platforms (and DT files). This patch adds bus
notifiers to be able to set the coherent DMA ops (with no cache
maintenance) for devices explicitly marked as coherent via the
"dma-coherent" DT property.
