drm/tegra: Changes for v6.4-rc1

The majority of this is minor cleanups and fixes. Other than those, this
contains Uwe's conversion to the new driver remove callback and Thomas'
fbdev DRM client conversion. The driver can now also be built on other
architectures to easy compile coverage.

Finally, this adds Mikko as a second maintainer for the driver. As a
next step we also want Tegra DRM to move into drm-misc to streamline the
maintenance process.

drm/tegra: Changes for v6.3-rc1

This set of changes includes a rework of the custom syncpoint interrupt
code to take better advantage of existing DRM/KMS infrastructure.

There's also various bits of cleanup and fixes included.

drm/tegra: Changes for v6.2-rc1

This contains a bunch of cleanups across the board as well as support
for the NVDEC hardware found on the Tegra234 SoC.

drm/tegra: Fixes for v6.1-rc6

This contains a single fix that avoids using the GART on Tegra20 because
it doesn't work well with the way the Tegra DRM driver tries to use it.

drm/tegra: Changes for v6.1-rc1

This contains a handful of small fixes, cleanups and improvements.

drm/tegra: Changes for v5.20-rc1

The bulk of these changes adds support for context isolation for the
various supported host1x engines, as well as support for the hardware
found on the new Tegra234 SoC generation.

There's also a couple of fixes and cleanups. To round things off, the
device tree bindings are converted to the new json-schema format that
allows DTBs to be validated.

drm/tegra: Preparatory work for v5.19

This contains a single patch from a series that's ready to go for v5.10
but is also a shared build-time dependency for an IOMMU series that is
planned for v5.20. The idea is to take this into v5.19 to fulfill that
dependency and remove the need for close coordination for the two
series.

drm/tegra: Changes for v5.19-rc1

Only a few fixes this time, and some debuggability improvements.

drm/tegra: Changes for v5.18-rc1

This contains a couple more minor fixes that didn't seem urgent enough
for v5.17. On top of that this improves YUV format support on older
chips.

drm/tegra: Fixes for v5.17-rc6

Contains a couple of fixes for Tegra186 suspend/resume, syncpoint
waiting, a build warning and eDP on older Tegra devices.

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.
