Subject: [PATCH] HACK: add KConfig to enable driver-specific color mgmt props
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. Replace the agreed name `AMD_PRIVATE_COLOR` with
our downstream version `CONFIG_DRM_AMD_COLOR_STEAMDECK`.

From: Joshua Ashton @ 2024-04-10 22:13 UTC (permalink / raw)
To: amd-gfx; +Cc: Joshua Ashton, Harry Wentland, Xaver Hugl, Melissa Wen, Ethan Lee
The comment here states "no OGAM in DPP since DCN1", yet that is not
true.
Testing on an RX 7900XTX (dcn32), it actually does exist in hardware and
works fine.
My best guess is the comment is confused with OGAM ROM for DPP, rather
than OGAM RAM.
I did not test dcn35/351 as I do not have that hardware, but I assume
the same follows there given the seemingly erroneous comment.
Someone at AMD should check that before merging this commit.
