From fcf3a6ef4a588c9f06ad7b01c83534ab81985a3f Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen Date: Mon, 15 Aug 2011 23:21:41 +0300 Subject: [PATCH] omap: iommu/iovmm: move to dedicated iommu folder Move OMAP's iommu drivers to the dedicated iommu drivers folder. While OMAP's iovmm (virtual memory manager) driver does not strictly belong to the iommu drivers folder, move it there as well, because it's by no means OMAP-specific (in concept. technically it is still coupled with OMAP's iommu). Eventually, iovmm will be completely replaced with the generic, iommu-based, dma-mapping API.
