From: Daniel Vetter Date: Tue, 3 Sep 2013 18:40:36 +0000 (+0200) Subject: drm/i915: handle sdvo input pixel multiplier correctly again X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eeb4793779060e0ae27fc8a85b8dac2ab3620934;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: handle sdvo input pixel multiplier correctly again The sdvo input timing needs to be the actual mode, the sdvo encoder automatically adjusts for the need of pixel doubling or quadrupling. This was lost in pipe config conversion of the pixel multiplier in commit 6cc5f341b5830541a1b6945435ca90c69b1b8b21 Author: Daniel Vetter Date: Wed Mar 27 00:44:53 2013 +0100 drm/i915: add pipe_config->pixel_multiplier While at it ditch the intel_ prefix from the crtc in intel_sdvo_mode_set.
