Subject: drm/i915: Add support for the YCbCr COLOR_RANGE property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: c8624ede3ed3b9f46364f5239c402393ec853e00
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Add support for the COLOR_RANGE property on planes. This property
selects whether the input YCbCr data is to treated as limited range
or full range.
On most platforms this is a matter of setting the "YUV range correction
disable" bit, and on VLV/CHV we'll just have to program the color
correction logic to pass the data through unmodified.
v2: Rebase
