From 85cb48a1651ee7cbc49468776d3078418f7827c5 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 9 Aug 2016 17:04:13 +0200 Subject: [PATCH] drm/i915: Convert intel_dp to use atomic state Slightly less straightforward. Some of the drrs calls are done from workers or from intel_ddi.c, pass along crtc_state when we can, or crtc->config when we can't.
