This patch series introduces a number of useful features for the Tegra DRM driver. Patch 1 is a documentation update and adds a warning to the page-flip IOCTL to catch buggy drivers that return success but failed to update the crtc->fb field, which would cause the reference counting to become unbalanced. Patch 2 adds support for the additional two planes available on Tegra hardware, while patch 3 implement .mode_set_base() to allow for some nice speed up when changing the framebuffer without actually changing the resolution. Patch 4 adds VBLANK support and patch 5 builds on the previous two to provide the page-flipping IOCTL. Patch 6 splits the DC_CMD_STATE_CONTROL register writes into two consecutive writes as required by the TRM. Finally patch 7 adds a new file, named "framebuffers" to debugfs which can be used to dump a list of framebuffers attached to the DRM device. This is most useful to inspect the reference count but could also be helpful in diagnosing out-of-memory conditions and such.
