From b2354c78b1251719f38775b27837fc39e25e3d35 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Thu, 4 Oct 2018 11:45:57 +0200 Subject: [PATCH] drm/i915: Make pll functions take crtc_state, v2. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of passing crtc and dereferencing crtc->config, passs the correct crtc_state and obtain the crtc pointer from there. Changes since v1: - Move vlv/chv changes and i9xx_set_pll_dividers changes from crtc_enable/disable patches to here. - Add commit message.
