From 53b41837935a4016852b30a6242a510e6927f9c7 Mon Sep 17 00:00:00 2001 From: Yuly Novikov Date: Fri, 26 Oct 2012 12:04:00 +0300 Subject: [PATCH] drm/i915/dp: allow configuring eDP panel fitting scaling mode LVDS allowed changing panel fitting scaling mode, while eDP didn't. Copied relevant code from LVDS to eDP.
