This series adds Video-Image-Compositor (VIC) support for Tegra124. The unit replaced gr2d engine on T124 and it is effectively used for similar operations: making simple surface copy and fill operations.
The series consists of four patches: The first patch fixes an issue in the host1x submit routine which has prevented using same buffer object for multiple command buffers. The second patch makes a simple improvement to the firewall to allow implementing address register validator for VIC. The last two patches in the series make the real modifications to Tegra DRM and device tree to enable the engine on T124.
The series has been tested on Jetson TK1 by first disabling IOMMU (*), enabling CMA and running a VIC clear test case that is posted to dri-devel and linux-tegra mailing lists. The firmware image for VIC is publicly available as part of Linux For Tegra driver package [0].

(*) Currently Tegra DRM does not support mapping the host1x command buffers into kernel address space in case IOMMU is enabled.
