Subject: [RFC PATCH 03/40] drm/amd/display: introduce Steam Deck color features to AMD display driver
Date:   Sun, 23 Apr 2023 13:10:15 -0100

We are enabling a large set of color calibration features to enhance KMS
color mgmt but these properties are specific of AMD display HW, and
cannot be provided by other vendors. Therefore, set a config option to
enable AMD driver-private properties used on Steam Deck color mgmt
pipeline.
