Cover letter [RFC v3 0/4] SMMUv3 Driver
This RFC addresses the review comments from the last RFC [1].
All the IORT realted changes have been droped in this version as these will be covered by [2]. The IORT implementation had to provide a Linux like API to the SMMUv3 driver.
List of changes:
- Addition of a linux_compat header.
- Addition of a common header for arm smmu defines.
- Rebase of the SMMUv3 driver to the driver in linux kernel 4.14 rc7.
