This patch series adds properties for plane color features. It adds
properties for degamma used to linearize data, CSC used for gamut
conversion, and gamma used to again non-linearize data as per panel
supported color space. These can be utilize by user space to convert
planes from one format to another, one color space to another etc.

Usersapce can take smart blending decisions and utilize these hardware
supported plane color features to get accurate color profile. The same
can help in consistent color quality from source to panel taking
advantage of advanced color features in hardware.

These patches just add the property interfaces and enable helper
functions.

This series adds Intel Gen9 specific plane gamma feature. We can
build up and add other platform/hardware specific implementation
on top of this series

Note: This is just to get a design feedback whether these interfaces
look ok. Based on community feedback on interfaces, we will implement
IGT tests to validate plane color features. This is un-tested currently.

Userspace implementation using these properties have been done in drm
hwcomposer by "Alexandru-Cosmin Gheorghe alexandru-cosmin.gheor...@arm.com"
from ARM. A merge request has been opened by Alexandru for drm_hwcomposer,
implementing the property changes for the same. Please review that as well:
https://gitlab.freedesktop.org/drm-hwcomposer/drm-hwcomposer/merge_requests/25

v2: Dropped legacy gamma table for plane as suggested by Maarten. Added
Gen9/BDW plane gamma feature and rebase on tot.

v3: Added a new drm_color_lut_ext structure to accommodate 32 bit precision
entries, pointed to by Brian, Starkey for HDR usecases. Addressed Sean,Paul
comments and moved plane color properties to drm_plane instead of
mode_config. Added property documentation as suggested by Daniel, Vetter.
Fixed a rebase fumble which occurred in v2, pointed by Emil Velikov.

v4: Rebase

v5: Added "Display Color Hardware Pipeline" flow to kernel
documentation as suggested by "Ville Syrjala" and "Brian Starkey".
Moved the property creation to drm_color_mgmt.c file to consolidate
all color operations at one place. Addressed Alexandru's review comments.

v6: Rebase. Added support for ICL Color features. Enhanced Lut precision to
accept input values in u32.32 format. This is needed for higher precision
required in HDR data processing.

v7: Fixed Lut roundup and extraction function in patch 1 and address
definitions for Degamma index in patch 10. Rest of the patches are just
rebased.

Uma Shankar (16):
  drm: Add Enhanced Gamma LUT precision structure
  drm: Add Plane Degamma properties
  drm: Add Plane CTM property
  drm: Add Plane Gamma properties
  drm: Define helper function
