From ccf3a35797a76e9a030b0f0a19dc2be9c8da4b7c Mon Sep 17 00:00:00 2001 From: Vitaly Prosyak Date: Fri, 15 Jun 2018 08:34:10 -0500 Subject: [PATCH 4953/5725] drm/amd/display: Add headers for hardcoded 1d luts. Hard-coded luts are needed since complex algorithms are used for color and tone mapping. Add the headers for future use.
