* drm/tegra: Sanitize format modifiersThierry Reding2018-03-091-17/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing format modifier definitions were merged prematurely, and recent work has unveiled that the definitions are suboptimal in several ways: - The format specifiers, except for one, are not Tegra specific, but the names don't reflect that. - The number space is split into two, reserving 32 bits for some "parameter" which most of the modifiers are not going to have. - Symbolic names for the modifiers are not using the standard DRM_FORMAT_MOD_* prefix, which makes them awkward to use. - The vendor prefix NV is somewhat ambiguous. Fortunately, nobody's started using these modifiers, so we can still fix the above issues. Do so by using the standard prefix. Also, remove TEGRA from the name of those modifiers that exist on NVIDIA GPUs as well. In case of the block linear modifiers, make the "parameter" smaller (4 bits, though only 6 values are valid) and don't let that leak into any of the other modifiers. Finally, also use the more canonical NVIDIA instead of the ambiguous NV prefix. This is based on commit 268892cb63a822315921a8dab48ac3e4abf7dd03 from Linux v4.16-rc1.

* intel: Move the DRM uapi headers to a non-Intel location.Eric Anholt2017-07-121-0/+379
I want to remove vc4's dependency on headers from libdrm as well, but storing multiple copies of drm_fourcc.h in our tree would be silly. v2: Update Android.mk as well, move distcheck drm*.h references to top-level noinst_HEADERS.
