486a45c2a6 drm/nouveau/i2c: do parsing of i2c-related vbios info in nouveau_i2c.c
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.

e0cd360813 gpu: add module.h to drivers/gpu files as required.
So that we don't get build failures once the implicit module.h
presence is removed.

c020c9a8ca drm/nv50: use custom i2c algo for dp auxch
This makes it easier to see how this is working, and lets us transfer the
EDID in blocks of 16 bytes.

The primary reason for this change is because debug logs are rather hard
to read with the hundreds of single-byte auxch transactions that occur.

f1feda70b5 drm/nouveau: Put back the old 2-messages I2C slave test.
I was hoping we could detect I2C devices at a given address without
actually writing data into them, but apparently some DDC slaves get
confused with 0-bytes transactions. Put the good old test back.

6d416d80f7 drm/nouveau: Add some generic I2C gadget detection code.
Clean up and move the external TV encoder detection code to
nouveau_i2c.c, it's also going to be useful for external TMDS and DDC
detection.

7e99a9b2b5 drm/nv50: fix monitor detection on certain chipsets
There appears to be some kind of switch on certain chips to control whether
the DP auxch or traditional i2c bus will be operational on a connector,
this commit hopefully fixes nouveau to do the right thing.

Likely only relevent on chips with DP outputs.

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.
