This series adds IOMMU support to Host1x and TegraDRM and adds support for the VIC (Video Image Compositor) host1x client. The series is available as a git repository at git://github.com/cyndis/linux.git; branch vic-2. A userspace test case for VIC can be found at https://github.com/cyndis/drm/tree/work/tegra. The testcase is in tests/tegra and is called submit_vic. The testcase/TRM include full headers and documentation to program the unit. The unit by itself, however, does not readily map to existing userspace library interfaces, so implementations for those are not provided. The in-kernel firewall is not implemented for VIC; therefore, either the IOMMU must be enabled or the firewall disabled for the test to pass. Tested with Jetson TX1 (T210). Probably works also with Jetson TK1 (T124). Note that due to hardware changes the testcase also needs to be changed to run properly on T124: this can be done by removing the topmost commit of the aforementioned test repository. Thanks, Mikko.
