From b4ede6dfa0c5a952161bac6c5f840469a13386ce Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 2 Mar 2017 19:15:01 +0200 Subject: [PATCH] drm/i915: Only use update_wm_{pre,post} for pre-ilk platforms MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that vlv/chv have more proper wm programming support, let's reduce the the update_wm_{pre,post} flags to only cover the pre-ilk platforms. When we finally convert those as well we can drop these flags entirely.
