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.

/*
* The following is some guesswork on how the TV encoder flicker
* filter/rescaler works:
*
* It seems to use some sort of resampling filter, it is controlled
* through the registers at NV_PTV_HFILTER and NV_PTV_VFILTER, they
* control the horizontal and vertical stage respectively, there is
* also NV_PTV_HFILTER2 the blob fills identically to NV_PTV_HFILTER,
* but they seem to do nothing. A rough guess might be that they could
* be used to independently control the filtering of each interlaced
* field, but I don't know how they are enabled. The whole filtering
* process seems to be disabled with bits 26:27 of PTV_200, but we
* aren't doing that.
*
* The layout of both register sets is the same:
*
* A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40]
* B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c]
*
* Each coefficient is stored in bits [31],[15:9] in two's complement
* format. They seem to be some kind of weights used in a low-pass
* filter. Both A and B coefficients are applied to the 14 nearest
* samples on each side (Listed from nearest to furthermost. They
* roughly cover 2 framebuffer pixels on each side). They are
* probably multiplied with some more hardwired weights before being
* used: B-coefficients are applied the same on both sides,
* A-coefficients are inverted before being applied to the opposite
* side.
*
* After all the hassle, I got the following formula by empirical
* means...
