Subject: [PATCH] drm/edid: VSDB yCBCr420 Deep Color mode bit definitions
Date: Fri, 5 Oct 2018 14:52:15 -0700 [thread overview]
Message-ID: <1538776335-12569-1-git-send-email-clinton.a.taylor@intel.com> (raw)
From: Clint Taylor <clinton.a.taylor@intel.com>
HDMI Forum VSDB YCBCR420 deep color capability bits are 2:0. Correct
definitions in the header for the mask to work correctly.
