From f75195cac32bfd2ef07764bd370d3b788bd8b003 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 12 Aug 2013 11:24:05 -0400 Subject: [PATCH] drm/radeon/dpm: add reclocking quirk for ASUS K70AF The LCD has a relatively short vblank time (216us), but the card is able to reclock memory fine in that time.
