Subject: [PATCH 2/4] drm/i915: Enable panel fitting for eDP
Date: Mon, 19 Jul 2010 09:43:12 +0100	[thread overview]
Message-ID: <1279528994-5621-3-git-send-email-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <1279528994-5621-1-git-send-email-chris@chris-wilson.co.uk>

From: Zhao Yakui <yakui.zhao@intel.com>

When trying to set other display mode besides the fixed panel mode, the
panel fitting should be enabled. This is similar to LVDS.
