git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
There's really not a great deal this time due to me spending most of this window on Maxwell. But, here's the random bits and pieces that's currently queued.
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (25 commits)

Cards with nv04 display engine can't reliably use vblank
counts and timestamps computed via drm_handle_vblank(), as
the function gets invoked after sending the pageflip events.
Fix this by defaulting to the old crtcid = -1 fallback path
on <= NV-50 cards, and only using the precise path on NV-50
and later.

Whenever a single nouveau_mc_intr() main gpu irq-handler invocation was
responsible for calling both, the vblank-irq handler (display engine irq)
and kms-pageflip completion handler (from fifo irq), the order of
invocation was wrong. nouveau_finish_flip() was called before
drm_handle_vblank() for the vblank of pageflip completion, so the
emitted pageflip event contained stale vblank count and timestamp
from previous vblank. This caused failure in userspace to timestamp
properly.
Reorder order of invocation of engine irq handlers: Put
NVDEV_ENGINE_DISP always on top, and thereby before NVDEV_ENGINE_FIFO,
so that drm_handle_vblank() gets called to update vblank timestamps
and count before potential pageflip events make use of that
information.
This works on nv-50 and later, where kms-pageflip completion triggers
an irq either after a separate vblank irq, or both pageflip and vblank
trigger one common irq invocation, but never before vblank irqs.
v2 (Ben):

nv04_disp_scanoutpos() must abort to trigger simple timestamping
fallback if vtotal/htotal regs return zero. This happens if the
output isn't a digital output, but a vga analog output, as the
regs don't get initialized in that case.
Fixes timestamping failure on nv-40 and earlier with vga output.

I spent some time this weekend trying to find in the vbios the number of
pulses per revolutions in the vbios but couldn't find it. It would seem
all my cards have 2 pulses per revolution so let's stick to that until
further notice.
Thermal table's id 0x48 may indicate this information but it would seem
that changing the value results in the blob power or clock gating the
RPM counter... We should ask NVIDIA about that, should be trivial-enough
for them to answer.

nvc0_graph_ctor() would only let the graphics engine be enabled if its
oclass has a proper microcode linked to it. This prevents GR from being
enabled at all on chips that rely exclusively on external firmware, even
though such a use-case is valid.
Relax the conditions enabling the GR engine to also include the case
where an external firmware has also been loaded.
Also switch to external firmware if the graph class has no microcode
linked to it.

drm/panel: Changes for v3.16-rc1
This set of commits contains a couple of fixes to existing panel drivers
and support for some new panels.
One commit touches the DRM core in that in modifies the MIPI DSI support
to hook up the shutdown function so that drivers can provide code that's
run on shutdown. This is used by a subsequent commit to make the simple
panel driver power off the backlight on shutdown.

drm/tegra: Changes for v3.16-rc1
The majority of these changes are a slew of cleanups across the board.
A more noteworthy change is the addition of drm_dev_set_unique() and the
conversion of the Tegra DRM driver to use it. This allows us to get rid
of the host1x drm_bus implementation. Other USB and platform drivers can
be changed in a similar way. Unfortunately for most PCI devices there is
some userspace that relies on the old functionality and cannot be as
easily converted.
HDMI and hardware cursor support is added for Tegra124. The SOR output
gains support for exposing CRCs via debugfs, which can be used for
automated testing. Many values that were hardcoded in the SOR/eDP code
are now computed at runtime to increase compatibility with more devices.
