c7ca4d1b6b drm/nouveau: make vbios parser runnable from an atomic context
The nv50 display isr bh needs to be converted to a tasklet, which means
we can't sleep anymore.  The places we execute vbios init tables are
rare, and not in any way performance critical, so this isn't a huge
problem.

855a95e4fc drm/nouveau: make the behaviour of get_pll_limits() consistent
This replaces all the pll_types definitions for ones that match the types
used in the tables in recent VBIOS versions.

get_pll_limits() will now accept either type or register value as input
across all limits table versions, and will store the actual register ID
that a PLL type refers to in the returned structure.

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.

67eda20e6b drm/nv04-nv3x: Implement init-compute-mem.
Init-compute-mem was the last piece missing for nv0x-nv3x card
cold-booting. This implementation is somewhat lacking but it's been
reported to work on most chipsets it was tested in. Let me know if it
breaks suspend to RAM for you.

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".

f3bbb9ccbf drm/nv40: rework lvds table parsing
All indications seem to be that the version 0x30 table should be handled
the same way as 0x40 (as used on G80), at least for the parts that we
currently try use.

This commit cleans up the parsing to make it clearer about what we're
actually trying to achieve, and unifies the 0x30/0x40 parsing.

d544d623c5 drm/nv50: fix connector table parsing for some cards
The connector table index in the DCB entry for each output type is an
index into the connector table, and does *not* necessarily match up
with what was previously called "index" in the connector table entries
themselves.

Not real sure what that index is exactly, renamed to "index2" as we
still use it to prevent creating multiple TV connectors.

39c9bfb453 drm/nv50: prevent multiple init tables being parsed at the same time
With DVI and DP plugged, the DVI clock change interrupts being run can
cause DP link training to fail.  This adds a spinlock around init table
parsing to prevent this.

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.
