22336de810 drm/tegra: Update to Linux v6.15-rc3 
Update the Tegra DRM to align with Linux v6.15-rc3. In Linux v6.15-rc3,
the arguments of the 'mode_valid' function pointer of the
drm_connector_helper_funcs structure and the 'atomic_async_check'
function pointer of the drm_plane_helper_funcs structure were updated.
Add conftest tests to detect these updates and make the necessary
changes to the Tegra DRM driver.

540737a228 drm/tegra: Update to Linux v6.13 
Update the Tegra DRM driver to align with Linux v6.13. A function
pointer 'fbdev_probe' was added to the drm_driver structure in Linux
v6.13 and so use conftest to detect this and make the necessary changes
to the Tegra DRM driver.

6be033ba85 drm/tegra: Update to Linux v6.12 
Update Tegra DRM to align with Linux v6.12. The output.c driver was
updated to use the 'drm_edid_connector_add_modes()' function that was
first added in Linux v6.3. Use conftest to detect the presence of the
drm_edid_connector_add_modes() function and make the necessary changes
to the driver.

f01227d4ea drivers: Drop inline from driver remove wrapper 
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the

8d5286c379 gpu/drm: tegra: Fix build for Linux v6.8 
Building the Tegra DRM driver with Linux v6.8 fails with the following
error ...

 drivers/gpu/drm/tegra/hdmi.c:623:25: error: implicit declaration of
 function ‘drm_eld_size’; did you mean ‘mm_cid_size’?
 [-Werror=implicit-function-declaration]
  623 |    size_t length = drm_eld_size(hdmi->output.connector.eld), i;
      |                    ^~~~~~~~~~~~

Commit ("8eb80946ab0c drm/edid: split out drm_eld.h from drm_edid.h")
added the header file 'drm/drm_eld.h' which now needs to be included to
build the Tegra DRM driver. Fix the build issue by using conftest to
detect the presence of the header 'drm/drm_eld.h' and include this
header if present.

b8c2d943ed drm/tegra: Add upstream tegra-drm driver 
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.
