From 5d02626d3167cd4214bf611362e08dfd1e98c62e Mon Sep 17 00:00:00 2001 From: Mario Kleiner Date: Thu, 5 Jun 2014 09:52:10 -0400 Subject: [PATCH] drm/edid: Store all supported hdmi deep color modes in drm_display_info HDMI deep color setup must know which modes are supported if it needs to degrade gracefully, as only 12 bpc / dc_36 is guaranteed, but 10 bpc / dc_30 is optional. The maximum bpc is not sufficient for this.
