From 23bd15ec662344dc10e9918fdd0dbc58bc71526d Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 14 Dec 2011 21:10:06 -0200 Subject: [PATCH 1/8] drm/i915: Fix TV Out refresh rate. TV Out refresh rate was half of the specification for almost all modes. Due to this reason pixel clock was so low for some modes causing flickering screen.
