As long as the subcomponents in the engine are active, we consider the
engine as active and the engine should export active signal to the
actmon.

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.

1. Commit 650f2dc97053 ("gpiolib: of: remove
   [devm_]gpiod_get_from_of_node() APIs")
2. Commit 6c80a93be62d ("drm/fb-helper: Initialize fb-helper's preferred
   BPP in prepare function")
3. Commit bc292ab00f6c ("(HEAD) mm: introduce vma->vm_flags wrapper
   functions")

Address the above to fix building the driver for Linux v6.3.

5dad8295a6 gpu: host1x: Fix build for Linux v6.3 
Upstream Linux commit ("1369459b2e21 iommu: Add a gfp parameter to
iommu_map()") adds a new parameter to the iommu_map function and this
breaks building the host1x driver with Linux v6.3.

Upstream Linux commit 2a81ada32f0e ("driver core: make struct
bus_type.uevent() take a const *") updates the uevent function pointer
type to make the device structure const which also breaks building the
host1x driver with Linux v6.3.

Address both of these issues to fix building the host1x driver with
Linux v6.3.

0c4db82587 drm/tegra: Fix check for undefined submit flags 
Fix the downstream-specific check for undefined submit flags to use
bitwise negation instead of logical. The author appears to have
written enough Rust to forget about bitwise negation using a different
operator.

e837f4e112 drm/tegra: Fix build for Linux v6.2 
Linux v6.2 makes the following changes in the DRM subsystem ...

1. Commit 7c99616e3fe7 ("drm: Remove drm_mode_config::fb_base") removes
   the fb_base member from the drm_mode_config structure.
2. Commit 9877d8f6bc37 ("drm/fb_helper: Rename field fbdev to info in
   struct drm_fb_helper") renames the 'fbdev' field of the drm_fb_helper
   structure to 'info'.
3. Commit 7fd50bc39d12 ("drm/fb-helper: Rename drm_fb_helper_alloc_fbi()
   to use _info postfix") renames the function drm_fb_helper_alloc_fbi()
   to drm_fb_helper_alloc_info().
4. Commit afb0ff78c13c ("drm/fb-helper: Rename drm_fb_helper_unregister_fbi() to
   use _info postfix") renames the function
   drm_fb_helper_unregister_fbi() to drm_fb_helper_unregister_info().

Update the Tegra DRM out-of-tree module as necessary to fix the build
for Linux v6.2.

e1b1afaab1 gpu: host1x: Select context device based on attached IOMMU 
On Tegra234, engines that are programmed through Host1x channels can
be attached to either the NISO0 or NISO1 SMMU. Because of that, when
selecting a context device to use with an engine, we need to select
one that is also attached to the same SMMU.

Add a parameter to host1x_memory_context_alloc to specify which device
we are allocating a context for, and use it to pick an appropriate
context device.

35730e5e7b gpu: host1x: External timeout/cancellation for fences 
Currently all fences have a 30 second timeout to ensure they are
cleaned up if the fence never completes otherwise. However, this
one size fits all solution doesn't actually fit in every case,
such as syncpoint waiting where we want to be able to have timeouts
longer than 30 seconds. As such, we want to be able to give control
over fence cancellation to the caller (and maybe eventually get rid
of the internal timeout altogether).

Here we add this cancellation mechanism by essentially adding a
function for entering the timeout path by function call, and changing
the syncpoint wait function to use it.
