From a4945f9522d27e1e6d64a02ad055e83768cb0896 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 8 Oct 2013 11:16:59 +0100 Subject: [PATCH] drm/i915: Undo the PIPEA quirk for i845 The PIPEA quirk is specifically for the issue with the PIPEB PLL on 830gm being slaved to the PIPEA PLL, and so to use PIPEB requires PIPEA running. i845 doesn't even have the second PLL or pipe, and enabling the quirk results in a blank DVO LVDS.
