Hi Dave, Daniel,

The following changes since commit 136057256686de39cc3a07c2e39ef6bc43003ff6:

  Linux 5.16-rc2 (2021-11-21 13:47:39 -0800)

  drm/tegra: Add back arm_iommu_detach_device() (2021-12-16 14:30:45 +0100)

This is unusually big because it contains essentially two cycles' worth
of work. I'm still not sure what happened for v5.16-rc1, but the PR was
never merged.

Fingers crossed that it will work better this time.

As mentioned last time already, the userspace for the new NVDEC driver
can be found here:

Thanks,

drm/tegra: Changes for v5.17-rc1

This contains a fairly large rework that makes the buffer objects behave
more according to what the DMA-BUF infrastructure expects. A buffer
object cache is implemented on top of that to make certain operations
such as page-flipping more efficient by avoiding needless map/unmap
operations. This in turn is useful to implement asynchronous commits to
support legacy cursor updates.

Another fairly big addition is the NVDEC driver. This uses the updated
UABI introduced in v5.15-rc1 to provide access to the video decode
engines found on Tegra210 and later.

This also includes some power management improvements that are useful on
older devices in particular because they, together with a bunch of other
changes across the kernel, allow the system to scale down frequency and
voltages when mostly idle and prevent these devices from becoming
excessively hot.

The remainder of these changes is an assortment of cleanups and minor
fixes.
