63901a1066 drm/tegra: Enable runtime PM during probe 
Currently, engine drivers only enable runtime PM during the host1x
init callback. This can happen slightly later than the probe, which
can cause the power domain to intermittently not be turned off after
probe.

My hypothesis is that there is a race condition between the post-probe
power domain poweroff that is done from a queued work, and the
pm_runtime_enable call happening in the host1x init callback.
If the pm_runtime_enable call happens first, everything is OK and
the power off work can disable the power domain as PM runtime is
enabled and the device is runtime suspended. If power off work runs
first, PM runtime is still disabled for the device and the domain
must be kept powered.

Resolve the issue by moving the runtime PM enablement to the
probe function.

e1ae7a73d5 drm/tegra: HACK: Avoid core kernel changes for NVDEC boot 
To allow NVDEC boot on T234 before core kernel changes are upstreamed,
apply hacks to directly read MC registers and hardcode firmware
descriptor information.

79282354d0 drm/tegra: Add Tegra234 support to NVDEC driver 
Add support for the Tegra234 version of NVDEC to the NVDEC driver.
This version sports a RISC-V controller and requires a few additional
clocks. After firmware has been loaded, the behavior is, however,
backwards compatible.

88c0b67c1d drm/tegra: Implement stream ID related callbacks on engines 
Implement the get_streamid_offset and can_use_memory_ctx callbacks
required for supporting context isolation. Since old firmware on VIC
cannot support context isolation without hacks that we don't want to
implement, check the firmware binary to see if context isolation
should be enabled.
