a4afff1535 drm/tegra: Register OFA as a devfreq device
Unit actmon is used to realize dynamic frequency scaling for OFA.
Therefore, registering OFA as one of devfreq devices to expose frequency
controllability to userspace.

1a32649b75 drm/tegra: Support client get_rate for OFA
When actmon reports the client usage information, it will call the
get_rate callback provided by the client, and divide the number of
sampled active clock cycles from the actmon counter register with the
current client rate to determine the client usage value.

5ad064a2bb drm/tegra: Enable runtime PM during probe for internal engines
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.

a9bb2f825b drm/tegra: Add OFA support
Add support for the optical flow accelerator. Implementation is the
same as for other Falcons except that we omit some legacy things
since the engine only exists from T234 onwards, and the addition
of having to initialize the OFA's safety RAM before boot.
