Modern sink devices support more than 1 type of colorspace like 601, 709, BT2020 etc. This helps to switch based on content type which is to be displayed. The decision lies with compositors as to in which scenarios, a particular colorspace will be picked. This will be helpful mostly to switch to higher gamut colorspaces like BT2020 when the media content is encoded as BT2020. Thereby giving a good visual experience to users. The expectation from userspace is that it should parse the EDID and get supported colorspaces. Use this property and switch to the one supported. Sink supported colorspaces should be retrieved by userspace from EDID and driver will not explicitly expose them. Basically the expectation from userspace is: - Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink colorspace - Set this new property to let the sink know what it converted the CRTC output to. v2: Addressed Maarten and Ville's review comments. Enhanced the colorspace enum to incorporate both HDMI and DP supported colorspaces. Also, added a default option for colorspace. v3: Removed Adobe references from enum definitions as per Ville, Hans Verkuil and Jonas Karlman suggestions. Changed Default to an unset state where driver will assign the colorspace is not chosen by user, suggested by Ville and Maarten. Addressed other misc review comments from Maarten. Split the changes to have separate colorspace property for DP and HDMI. v4: Addressed Chris and Ville's review comments, and created a common colorspace property for DP and HDMI, filtered the list based on the colorspaces supported by the respective protocol standard. v5: Made the property creation helper accept enum list based on platform capabilties as suggested by Shashank. Consolidated HDMI and DP property creation in the common helper. v6: Addressed Shashank's review comments. v7: Added defines instead of enum in uapi as per Brian Starkey's suggestion in order to go with string matching at userspace. Updated the commit message to add more details as well kernel docs. v8: Addressed Maarten's review comments. v9: Removed macro defines from uapi as per Brian Starkey and Daniel Stone's comments and moved to drm include file. Moved back to older design with exposing all HDMI colorspaces to userspace since infoframe capability is there even on legacy platforms, as per Ville's review comments. v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack. v11: Addressed Ville's review comments. Updated the Macro naming and added DCI-P3 colorspace as well defined in CEA 861.G spec.

Based on colorspace change, modeset will be triggered to switch to new colorspace. Based on colorspace property value create an infoframe with appropriate colorspace. This can be used to send an infoframe packet with proper colorspace value set which will help to enable wider color gamut like BT2020 on sink. This patch attaches and enables HDMI colorspace, DP will be taken care separately. v2: Merged the changes of creating infoframe as well to this patch as per Maarten's suggestion. v3: Addressed review comments from Shashank. Separated HDMI and DP colorspaces as suggested by Ville and Maarten. v4: Addressed Chris and Ville's review comments, and created a common colorspace property for DP and HDMI, filtered the list based on the colorspaces supported by the respective protocol standard. Handle the default case properly. v5: Merged the DP handling along with platform colorspace handling as per Shashank's comments. v6: Reverted to old design of exposing all colorspaces to userspace as per Ville's review comment v7: Fixed a checkpatch complaint, Addressed Maarten' review comment, updated the RB from Maarten and Jani's ack. v8: Moved colorspace AVI Infoframe programming to drm core and removed from driver as per Ville's suggestion.
