Subject: [PATCH v5 2/9] dma-mapping: add {map,unmap}_resource to dma_map_ops
Date: Tue,  8 Mar 2016 03:42:47 +0100	[thread overview]
Message-ID: <1457404974-1800-3-git-send-email-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <1457404974-1800-1-git-send-email-niklas.soderlund+renesas@ragnatech.se>

Add methods to handle mapping of device resources from a physical
address. This is needed for example to be able to map MMIO FIFO
registers to a IOMMU.
