Subject: [PATCH 3/9] drm/msm/mdp: mdp4: Update LCDC/LVDS port parsing
Date: Tue,  3 May 2016 16:27:55 +0530	[thread overview]
Message-ID: <1462273081-5814-4-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1462273081-5814-1-git-send-email-architt@codeaurora.org>

The LCDC port is the first in the list of the output ports in MDP4.
Mention this explicitly in the driver.
