8a28999d28 drm/tegra: Drop kernel version checks 
Drop the kernel version checks from Tegra DRM because these are only
needed for pre-Linux v6.x kernels and these are no longer supported.

43cafba95d drm/tegra: Fix support for Linux v5.10 
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
 [-Werror=incompatible-pointer-types]
  .atomic_check = tegra_crtc_atomic_check,
                  ^~~~~~~~~~~~~~~~~~~~~~~

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.

1da27ee38f drm/tegra: Implement buffer object cache 
This cache is used to avoid mapping and unmapping buffer objects
unnecessarily. Mappings are cached per client and stay hot until
the buffer object is destroyed.

756aa327f1 drm/tegra: Implement correct DMA-BUF semantics 
DMA-BUF requires that each device that accesses a DMA-BUF attaches to it
separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions
need to be reimplemented so that they can return a mapping, which either
represents an attachment or a map of the driver's own GEM object.

color format conversions in multimedia playback use-cases.

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.
