From 6cc5f341b5830541a1b6945435ca90c69b1b8b21 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 27 Mar 2013 00:44:53 +0100 Subject: [PATCH] drm/i915: add pipe_config->pixel_multiplier Used by SDVO (and hopefully, eventually HDMI, if we ever get around to fixing up the low dotclock CEA modes ...). This required adding a new encoder->mode_set callback to be able to pass around the intel_crtc_config.
