From 062efa5d841cca5e0df5b45c624966cb9936438c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 12 Apr 2016 22:14:36 +0300 Subject: [PATCH] drm/i915: Eliminate {vlv,bxt}_configure_dsi_pll() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fold the DSI PLL configuration functions into the DSI PLL enable functions since they are small and not called from anywhere else.
