Subject: [PATCH] drm/i915/chv: Update csc coefficient matrix during modeset
Date: Mon, 10 Sep 2018 18:31:22 +0530	[thread overview]
Message-ID: <1536584482-12894-1-git-send-email-raviraj.p.sitaram@intel.com> (raw)

From: P Raviraj Sitaram <raviraj.p.sitaram@intel.com>

During modeset, previously configured csc coefficient matrix,if any, will
not persist. This can result in blank screen as csc mode will be programmed
while loading LUT but csc coefficient matrix remains unprogrammed.
