Subject: [v3 0/7] Add Multi Segment Gamma Support
Date: Fri, 12 Apr 2019 15:50:56 +0530	[thread overview]
Message-ID: <1555064463-18479-1-git-send-email-uma.shankar@intel.com> (raw)

This series adds support for programmable gamma modes and
exposes a property interface for the same. Also added,
support for multi segment gamma mode introduced in ICL+

It creates GAMMA_MODE property interface. This is an enum
property with values as blob_id's and exposes
the various gamma modes supported and the lut ranges  Getting the
blob id in userspace, user can get the mode supported and
also the range of gamma mode supported with number of lut
coefficients. It can then set one of the modes using this
enum property.

Lut values will be sent through already available GAMMA_LUT
blob property.

It also introduces a CLIENT CAP for advanced GAMMA_MODE.
 This is for user to set the and use advance gamma mode and older
userspace can continue using the legacy paths.

v2: Used Ville's design and approach to define the interfaces.
Addressed Matt Roper's review feedback and re-ordered the
patches.

v3: Converged to 1 property interface and introduced a Client cap
as suggested by Ville. Fixed review comments received.
