From 30cf6db8b242e6bc7a660403471d2d78445f4860 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 24 Apr 2014 23:54:58 +0200 Subject: [PATCH] drm/i915/ddi: Remove ->mode_set callback A bit more care required here since there are some very few things between the call to encoder->mode_set and encoder->pre_enable. But they're either book-keeping or only matter for the vga port on the pch. So of no concern. Note that with the new sequence we write the infoframes after selecting the clock source, but that shouldn't matter. I've simply opted for this to have simpler code.
