Ben Skeggs fce2bad0ee drm/nv50: rework PGPIO IRQ handling and hotplug detection
Allows callers to install their own handlers for when a GPIO line
changes state (such as for hotplug detect).

This also fixes a bug where we weren't acknowledging the GPIO IRQ
until after the bottom half had run, causing a severe IRQ storm
in some cases.

Ben Skeggs 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.

There's one known case where we never stop recieving DEFER, and loop here
forever.  Lets not do that..

Maarten Maathuis ef2bb50668 drm/nouveau: use drm debug levels
- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

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.
