[PATCH 00/14] staging: media: tegra-vdea: Add Tegra124 support

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

Hi,

this set of patches perform a bit of cleanup and extend support to the
VDE implementation found on Tegra114 and Tegra124. This requires adding
handling for a clock and a reset for the BSEV block that is separate
from the main VDE block. The new VDE revision also supports reference
picture marking, which requires that the BSEV writes out some related
data to a memory location. Since the supported tiling layouts have been
changed in Tegra124, which supports only block-linear and no pitch-
linear layouts, a new way is added to request a specific layout for the
decoded frames. Both of the above changes require breaking the ABI to
accomodate for the new data in the custom IOCTL.

Finally this set also adds support for dealing with an IOMMU, which
makes it more convenient to deal with imported buffers since they no
longer need to be physically contiguous.

Userspace changes for the updated ABI are available here:

Mauro, I'm sending the device tree changes as part of the series for
completeness, but I expect to pick those up into the Tegra tree once
this has been reviewed and you've applied the driver changes.

Thanks,
Thierry
