Subject: [PATCH 5/9] drm/i915: split intel_dp_init into encoder and connector pieces
Date: Fri, 26 Oct 2012 19:05:48 -0200	[thread overview]
Message-ID: <1351285552-4156-6-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1351285552-4156-1-git-send-email-przanoni@gmail.com>

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Same reason as the previous HDMI commit: the DDI code will have its
own encoder init function but still use the DP and HDMI connectors.
