[PATCH v2 0/2] drm/msm/gem: Add metadata uapi

[Rob Clark]

From: Rob Clark <robdclark at chromium.org>

Add metadata mechanism to provide a back-channel to communicate image
layout information between vk and gl, because EXT_external_objects
doesn't support explicit modifiers and "OPTIMAL_TILING_EXT" is not
enough information for the importer to deduce the layout.
