From Arto's original cover letter:
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 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.
End of original cover letter.
The aforementioned VIC clear test can be found at https://patchwork.kernel.org/patch/6454821/.
This series is now composed of a commit that adds a general Falcon helper library to be used by drivers whose hardware contains a Falcon, which includes many Host1x clients; and then separately of the VIC driver that uses that Falcon library. The fixes to host1x this series used to include are in the 'Host1x/TegraDRM fixes/improvements' series I posted earlier; that series is a dependency for this series.
Thanks, Mikko.
