Re: [RFC PATCH 03/40] drm/amd/display: introduce Steam Deck color features to AMD display driver
I think the idea is that we wouldn't have a config option so it doesn't inherently become linux kernel uAPI? Then we can just build our SteamOS kernels with that definiton set.

I see, I'll follow this path. Still on that, I've changed CONFIG_STEAM_DECK (too generic) to CONFIG_DRM_AMD_COLOR_STEAMDECK. Does it sound better?

[RFC PATCH 03/40] drm/amd/display: introduce Steam Deck color features to AMD display driver
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.
