[PATCH v1 0/4] NVIDIA Tegra Video Decoder driver improvements

[Dmitry Osipenko]

Hello,

This series cleans up some of minor shortcomings that are caused by
checkpatch recommendations that are not very applicable for the driver.
Then IOMMU support is added to the driver and now it can handle sparse
memory buffers that GPU hands to VDE in a default kernel configuration
on Tegra30+.

Dmitry Osipenko (4):
  staging: media: tegra-vde: Remove BIT() macro from UAPI header
  staging: media: tegra-vde: Manually pack UAPI structures
  staging: media: tegra-vde: Add IOMMU support
  staging: media: tegra-vde: Defer dmabuf's unmapping
