Subject: [PATCH 0/7] Add Plane Color Properties
Date: Tue,  7 Nov 2017 17:36:24 +0530	[thread overview]
Message-ID: <1510056391-9684-1-git-send-email-uma.shankar@intel.com> (raw)

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. 

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