    Subject[PATCH 0/4] Add VIC support for Tegra124
    Date
    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.

    host1x: Pass register value in firewall
