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.
