This patch adds a colorspace connector property, enabling userspace to switch to various supported colorspaces. This will help enable BT2020 along with other colorspaces. 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.
