This patch series enables HDR support in drm. It basically defines HDR metadata structures, property to pass content (after blending) metadata from user space compositors to driver. Dynamic Range and Mastering infoframe creation and sending. ToDo: 1. We need to get the color framework in place for all planes which support HDR content in hardware. This is already in progres and patches are out for review in mailing list. 2. UserSpace/Compositors: Blending policies and metadata blob creation and passing to driver. Work is already in progress by Intel's middleware teams on wayland and the patches for the same are in review. A POC has already been developed by Ville based on wayland.
