Date: Wed, 19 Sep 2012 18:47:09 +0530 Message-ID: <1348060632-12997-1-git-send-email-b16395@freescale.com> MIME-Version: 1.0 Content-Type: text/plain Cc: Varun Sethi List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , From: Varun Sethi This patchset provides the Freescale PAMU (Peripheral Access Management Unit) driver and the corresponding IOMMU API implementation. PAMU is the IOMMU present on Freescale QorIQ platforms. PAMU can authorize memory access, remap the memory address, and remap the I/O transaction type. This set consists of the following patches: 1. Addition of new field in the device (powerpc) archdata structure for storing iommu domain information pointer. This pointer is stored when the device is attached to a particular iommu domain. 2. Addition of domain attributes required by the PAMU driver IOMMU API. 3. PAMU driver and IOMMU API implementation. Varun Sethi (3): Store iommu domain information pointer in archdata. Add iommu domain attributes required by fsl PAMU driver.
