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.

When the OFA driver was added for Tegra234, the driver was not added to
the list of drivers registered by the Tegra DRM driver. This is breaking
support for Tegra DRM. Add the OFA driver to the lists of driver to fix
Tegra DRM 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.

When compiling the Tegra DRM driver for Linux v5.10 it is currently
failing and the following errors are seen ...
tegra/dc.c: In function 'tegra_crtc_atomic_begin':
tegra/dc.c:2278:43: error: 'state' undeclared (first use in this function)
tegra_crtc_update_memory_bandwidth(crtc, state, true);

tegra/dc.c:2524:18: error: initialization from incompatible pointer type

^~~~~~~~~~~~~~~~~~~~~~~
Upstream commit 04d5d5df9df7 ("drm/tegra: dc: Support memory bandwidth
management") added support for memory bandwidth and so disable this for
Linux kernel prior to v5.11 due to incompatibilty with these earlier
versions.

Upstream commit c1736b9008cb ("drm: IRQ midlayer is now legacy") moved
the 'irq_enabled' member of struct drm_device under CONFIG_DRM_LEGACY.
When compiling Linux v5.15 without CONFIG_DRM_LEGACY enabled, compiling
the Tegra DRM driver now fails because the 'irq_enabled' member is not
defined.
Upstream commit 14746211570b ("drm/tegra: Don't set struct
drm_device.irq_enabled") has now removed the setting of the
'irq_enabled' variable from the Tegra DRM driver and so fix this by
only setting this variable for kernels prior to Linux v5.15.

Upstream commit be4306ad928f ("drm/tegra: Don't set allow_fb_modifiers
explicitly") removed the setting of drm->mode_config.allow_fb_modifiers
from the Tegra DRM driver because this is now set by the core. However,
because this is still being set in the Tegra DRM out-of-tree module it
generates a WARNING on boot. Fix this by not setting
drm->mode_config.allow_fb_modifiers for Linux kernels v5.14 and greater.
Upstream commit 6cba3fe43341 ("drm/dp: Add backpointer to drm_device in
drm_dp_aux") added a backpointer that if missing generates another
WARNING on boot so fix this by ensuring the backpointer is populated for
Linux v5.14 kernels and greater.

Commit 97c9bfe3f660 ("drm/aperture: Pass DRM driver structure instead
of driver name") updated the function drm_aperture_remove_framebuffers()
so that callers need to pass a DRM driver structure instead of a name.
This is causing the compilation of out-of-tree Tegra DRM driver to fail
for Linux v5.15 kernels. Update the out-of-tree Tegra DRM driver as
necessary to support v5.15 kernels.

For Linux v5.11, there are a some changes to the DRM APIs that require
updates to the Tegra DRM driver. These are:
1. Commit 6619ccf1bb1d ("dma-buf: Use struct dma_buf_map in
dma_buf_vmap() interfaces") changes to the dma_buf_vmap() and
dma_buf_vunmap() APIs to pass a new parameter of type
'struct dma_buf_map'.
2. Commit 351f950db4ab ("drm/atomic: Pass the full state to CRTC atomic
enable/disable) and commit f6ebe9f9c923 ("drm/atomic: Pass the full
state to CRTC atomic begin and flush") changes the structure type
passed to APIs referenced by the commits.
Finally, commit dd311c6fe8af ("drm/tegra: Introduce GEM object
functions") update the Tegra DRM driver to use GEM object functions.
Update the Tegra DRM driver to support these updated APIs for
Linux v5.11+ and align with the latest changes.

Add the upstream tegra-drm driver with the 'Host1x/Tegra UAPI' series
[0] applied. This driver will be built as an external module for testing
and development with upstream Linux kernels.
The following modifications have been made to the series posted upstream
1. Update the Makefile to always build the driver as a module
2. Always enable the tegra_drm_ioctl_xxx in the tegra_drm_ioctls and
remove the dependency on CONFIG_DRM_TEGRA_STAGING.
3. Rename the include/uapi/drm/tegra_drm.h to
include/uapi/drm/tegra_drm_next.h to avoid conflicts with upstream
headers when building as an external module.
5. Rename the module that is built to be tegra-drm-next.ko instead of
tegra-drm.ko to avoid any depmod conflicts with the upstream driver.
