From 96f90c5421aaaba35ffd931728fabeb8f6cd8471 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 5 Dec 2013 15:51:38 +0200 Subject: [PATCH] drm/i915: Move ILK/SNB/IVB over to the HSW WM code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The new HSW watermark code can now handle ILK/SNB/IVB as well, so switch them over. Kill the old code.
