From 3538b9dffd8344cd40413018bcd7dc7b2bc1e21d Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 1 Jun 2015 12:50:10 +0200 Subject: [PATCH] drm/i915: Use atomic state for calculating DVO_2X_MODE on i830. This is a small behavioral change because it leaves DVO_2X_MODE set between crtc_disable and crtc_enable. This is probably harmless though and if not should be fixed by calculating 2x mode before enable/disable pll. This is needed because intel_crtc->active will be removed eventually.
