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.
