[Nouveau] [PATCH v2 0/3] drm/nouveau: Support NVIDIA format modifiers

[James Jones]

This series modifies the NV5x+ nouveau display backends to advertise
appropriate format modifiers on their display planes in atomic mode
setting blobs.

Corresponding modifications to Mesa/userspace are available here:

https://gitlab.freedesktop.org/cubanismo/mesa/tree/nouveau_work

But those need a bit of cleanup before they're ready to submit.

I've tested this on Tesla, Kepler, Pascal, and Turing-class hardware
using various formats and all the exposed format modifiers, plus some
negative testing with invalid ones.

NOTE: this series depends on the "[PATCH v3] drm: Generalized NV Block
Linear DRM format mod" patch submitted to dri-devel.

v2: Used Tesla family instead of NV50 chipset compare to avoid treating
    oddly numbered NV4x-class chipsets as NV50+ GPUs.  Other instances
    of compares with chipset number in the series were audited, deemed
    safe, and left as-is for consistency with existing code.
