drm/tegra: Use more descriptive format modifiers

Commit Message

James Jones Dec. 17, 2019, 12:52 a.m. UTC

Advertise and accept both the existing
DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()-based format
modifiers and the more descriptive
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D()-based
format modifiers, preserving backwards
compatibility with existing userspace drivers, but
providing forwards compatibility with future
userspace drivers that also make use of the more
descriptive modifiers to enable differentiation
between desktop and tegra, as well as compressed
and non-compressed surfaces.

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