Hi Dave, Daniel,

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, Thierry
---------------------------------------------------------------- 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.
