327ceae664 drm/nv04-nv40: Fall back to panel rescaling if we have no usable native mode.
This allows the user to set a mode larger than the native one, useful
if we had trouble finding the actual native mode (e.g. because it goes
above the hardware bandwidth limits).

cd2fb2e9e0 drm/nv0x-nv4x: Leave the 0x40 bit untouched when changing CRE_LCD.
It's an unrelated PLL filtering control bit, leave it alone when

already set.

4a9f822fe1 drm/nv17-nv4x: Attempt to init some external TMDS transmitters.
sil164 and friends are the most common, usually they just need to be
poked once because a fixed configuration is enough for any modes and
clocks, so they worked without this patch if the BIOS had done a good
job on POST. Display couldn't survive a suspend/resume cycle though.
Unfortunately, BIOS scripts are useless here.

8f1a60868f drm/nouveau: tidy connector/encoder creation a little
Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector.  This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.

This can also potentially modify the connector ordering on nv50.  On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged.  However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

ef2bb50668 drm/nouveau: use drm debug levels
- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

6ee738610f drm/nouveau: Add DRM driver for NVIDIA GPUs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
