From 32f9d658aee5be09ebdd28fc730630e61d0b46db Mon Sep 17 00:00:00 2001 From: Zhenyu Wang Date: Fri, 24 Jul 2009 01:00:32 +0800 Subject: drm/i915: Add eDP support on IGDNG mobile chip This adds embedded DisplayPort support on next mobile chip which aims to replace origin LVDS port. VBT's driver feature block has been used to determine the type of current internal panel for eDP or LVDS. Currently no panel fitting support for eDP and backlight control would be added in future.
