From cf3e0fb48cdb62d6b30ec88eddcbfa82eb3e976a Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 29 Aug 2017 16:22:28 -0700 Subject: [PATCH] drm/i915/cnl: Move ddi buf trans related functions up. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit No functional changes. But those functions will be needed to get max level for HDMI and DP, so let's move those up closer to other similar functions existent for previous platforms.
