From 59df7b1771c150163e522f33c638096ab0efbf42 Mon Sep 17 00:00:00 2001 From: Christian Schmidt Date: Mon, 19 Dec 2011 20:03:33 +0100 Subject: [PATCH] drm/intel: Fix initialization if startup happens in interlaced mode [v2] My EFI BIOS starts the graphics card up in my projector's preferred EDID mode, 1080@60i. The Intel driver does not clear all the interlaced bits. This patch introduces a new PIPECONF_INTERLACE_MASK define and uses it to restore progressive mode.
