- moves out of nouveau_bios.c and demagics the logical state definitions
- simplifies chipset-specific driver interface
- makes most of gpio irq handling common, will use for nv4x hpd later
- api extended to allow both direct gpio access, and access using the
logical function states
- api extended to allow for future use of gpio extender chips
- pre-nv50 was handled very badly, the main issue being that all GPIOs
were being treated as output-only.
- fixes nvd0 so gpio changes actually stick, magic reg needs bashing

The DCB table provided by the VBIOS on most MXM chips has a number of
entries which either need to be disabled, or modified according to the
MXM-SIS Output Device Descriptors.
The x86 vbios code usually takes care of this for us, however, with the
large number of laptops now with switchable graphics or optimus, a lot
of the time nouveau is responsible for POSTing the card instead - leaving
some fun situations like, plugging in a monitor and having nouveau decide
3 connectors actually just got plugged in..
No MXM-SIS fetching methods implemented yet.

Another case where we parsed vbios data to some structs, then again use
that info once to construct another set of data. Skip the intermediate
step.
This is also slightly improved in that we can now use DCB 3.x connector
table info, which will allow NV4x to gain hotplug support, and to make
quirks for SPWG LVDS panels unnecessary.

Not much point parsing the vbios data into a struct which is only used once
to parse the data into another struct, go directly from vbios to
nouveau_i2c_chan.

This primary reason for this was mostly to avoid duplication of some of
this stuff by the MXM-SIS parser. However, some other cleanups will also
follow this as a result.

Following to "drm/nv50/pm: s/unk05/vdec/", let's rename the PLL to PLL_VDEC
PLL names are purely indicative and are based on the most important engine
it clocks.

Exposes the following sysfs entries:
- fan0_input: read the rotational speed of the fan (poll a bit during 250ms)
- pwm0: set the pwm duty cycle
- pwm0_min/max: set the minimum/maximum pwm value
v2 (Ben Skeggs):
- nv50 pwm controller code removed in favour of other more complete code
- FAN_RPM -> FAN_SENSE
- merged FAN_SENSE readout into common code, not at all nv50-specific
- protected fanspeed changes with perflvl_wr
- formatting tidying
- added some comments where things are shaky
v3 (Martin Peres)
- ensure duty min/max from thermal table are sane

Will need to be able to distinguish 2.0/2.1 from 3.0 soon. Also, move
the vbios parsing to nouveau_dp where it belongs.

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.

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.

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.

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.

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".

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.

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.

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

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.
