Ben Skeggs a002feceb7 drm/nouveau/dp: pass in required datarate to link training
Not used currently, but it will be used in preference to pre-determined
lane/bandwidth numbers at a later point.

Ben Skeggs 10b461e40a drm/nv50/backlight: take the sor into account when bashing regs
I'm sure that out there somewhere, someone will need this.  We currently
haven't seen an example of LVDS being on a non-0 SOR so far though.

Francisco Jerez 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.

Ben Skeggs ec7fc4a1a7 drm/nv50: supply encoder disable() hook for SOR outputs
Allows us to remove a driver hack that used to be necessary to disable
encoders in certain situations before setting up a mode.  The DRM has
better knowledge of when this is needed than the driver does.

This fixes a number of display switching issues.

Ben Skeggs 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".

Ben Skeggs 6f335a7afa drm/nv50: preserve an unknown SOR_MODECTRL value for DP encoders
This value interacts with some registers we don't currently know how to
program properly ourselves.  The default of 5 that we were using matches
what the VBIOS on early DP cards do, but later ones use 6, which would
cause nouveau to program an incorrect mode on these chips.

Ben Skeggs 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.
