I prepared a new patchset and it is ready for submitting. It includes several bugfixes and Exynos5 support. The last patche submitted has a bug when the following situation: 1. Allocating a 2nd level page table to map 4KB or 64KB on a virtual region 2. Unmapped all entries in the 2nd level page table. 3. Mapping to the same region with 1MB page. Then iommu_map() will return -EADDRINUSE due to incorrect counting free entries in 2nd level page table. The next patch will be submitted by 2/28. BTW Marek, I want to know why MFC driver defines separate platform devices for left and right buses. The next IOMMU driver defines just one platform device for a H/W device. Thus, it defines just one SYSMMU_MFC platform device, for example. (the previous one defines 2 platform devices for SYSMMU_MFC) However, it is easy to separate the single platform device to multiple platform devices.
