arm64: device: add iommu pointer to device archdata 2013-06-11T17:15:55+00:00 Will Deacon will.deacon@arm.com 2013-06-10T18:34:42+00:00 73150c983ac1f9b7653cfd3823b1ad4a44aad3bf When using an IOMMU for device mappings, it is necessary to keep a pointer between the device and the IOMMU to which it is attached in order to obtain the correct IOMMU when attaching the device to a domain. This patch adds an iommu pointer to the dev_archdata structure, in a similar manner to other architectures (ARM, PowerPC, x86, ...).

The __raw_* accessors are implemented as inline asm to avoid compiler generation of post-indexed accesses (less efficient to emulate in a virtualised environment).
