[v5,0/6] Add support for Gen 11 pipe color features

Message

Shankar, Uma Jan. 8, 2019, 7:37 a.m. UTC

This patch series adds support for Gen11 pipe degamma, CSC
and gamma hardware blocks.

CRC checks are not working for 10bit gamma but works for 8bit
pallete modes which seems to be due to some rounding errors in pipe.

ToDo: Support for Multi Segmented Gamma will be added later.

v2: Addressed Maarten's review comments and re-ordered the patch
series.

v3: Addressed Matt's review comments. Removed rmw patterns
as suggested by Matt.

v4: Addressed Matt's review comments.

v5: Addressed Matt's, Ville and Jani Nikula's review comments.
