Merge tag 'drm/tegra/for-5.13-rc1' of ssh://git.freedesktop.org/git/tegra/linux into drm-next
drm/tegra: Changes for v5.13-rc1
The changes this time around contain a couple of fixes for host1x along
with some improvements for Tegra DRM. Most notably the Tegra DRM driver
now supports the hardware cursor on Tegra186 and later, more correctly
reflects the capabilities of the display pipelines on various Tegra SoC
generations and knows how to deal with the dGPU sector layout by using
framebuffer modifiers.
