[Intel-gfx] [RFC 0/9] Add HDR Metadata Parsing and handling in DRM layer

[Uma Shankar]

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.
2. UserSpace/Compositors: Blending policies and metadata blob
   creation and passing to driver.

Please review and share your feedbacks/suggestions. 

Note: The intention for these patches is to get a design feedback on the uapi changes,
generic property design and infoframe handling. This cannot get merged as of now without
the userspace support in place. This series is not yet tested.

Uma Shankar (9):
  drm: Add HDR source metadata property
  drm: Add CEA extended tag blocks and HDR bitfield macros
  drm: Parse HDR metadata info from EDID
  drm: Parse Colorimetry data block from EDID
  drm/i915: Attach HDR metadata property to connector
  drm: Add HDR capabilty field to plane structure
  drm: Implement HDR source metadata set and get property handling
  drm: Enable HDR infoframe support
  drm/i915: Write HDR infoframe and send to panel
