fbce3f1d95 UPSTREAM: drm/tegra: hub: Fix YUV support 
The driver currently exposes several YUV formats but fails to properly
program all the registers needed to display such formats. Add the right
programming sequences so that overlay windows can be used to accelerate
color format conversions in multimedia playback use-cases.

f0231b05dc UPSTREAM: drm/tegra: Fix shift overflow in tegra_shared_plane_atomic_update 
Clang warns:

drivers/gpu/drm/tegra/hub.c:513:11: warning: shift count >= width of
type [-Wshift-count-overflow]
                base |= BIT(39);
                        ^~~~~~~

BIT is unsigned long, which is 32-bit on ARCH=arm, hence the overflow
warning. Switch to BIT_ULL, which is 64-bit and will not overflow.

d885fa7b15 UPSTREAM: drm/tegra: Support sector layout on Tegra194 
Tegra194 has a special physical address bit that enables some memory
swizzling logic to support different sector layouts. Support the bit
that selects the sector layout which is passed in the framebuffer
modifier.

9ca27f1245 UPSTREAM: drm/tegra: Count number of display controllers at runtime 
In order to be able to attach planes to all possible display controllers
the exact number of CRTCs must be known. Keep track of the number of the
display controllers that register during initialization.

efed2371e4 UPSTREAM: drm/tegra: dc: Inherit DMA mask 
Inherit the DMA mask from host1x (on Tegra210 and earlier) or the
display hub (on Tegra186 and later). This is necessary in order to
properly map buffers without SMMU support and use the maximum IOVA
space available with SMMU support.

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.
