From 62047d1e4a3b0e4114cd936af705a3ace95ab313 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Thu, 27 Aug 2015 15:07:03 +0200 Subject: gma: Consolidate Intel IGD ACPI code some more Consolidate some common (and mostly broken) code. Will try to fix things in separate commits. Maybe, igd.asl taken from gm45 (the non-PCH case) could also be used for i945 and sch. But this needs further investigation.
