doesn't explicitly check for them as long as they use the same depth.

603f0cc948 drm/tegra: Explicitly set irq_enabled 
Since the Tegra DRM driver doesn't use the drm_irq_install() helper, the
irq_enabled flag needs to be set manually in order to make functionality
such as the DRM_IOCTL_WAIT_VBLANK work properly.

de2ba664c3 gpu: host1x: drm: Add memory manager and fb 
This patch introduces a memory manager for tegra drm and moves
existing parts to use it. As cma framebuffer helpers can no more
be used, this patch adds also a separate framebuffer driver for
tegra.
