Subject: [PATCH v6 09/10] drm/mediatek: add support for Mediatek SoC MT2701
Date: Thu, 4 Aug 2016 19:07:23 +0800	[thread overview]
Message-ID: <1470308844-20895-10-git-send-email-yt.shen@mediatek.com> (raw)
In-Reply-To: <1470308844-20895-1-git-send-email-yt.shen@mediatek.com>

This patch add support for the Mediatek MT2701 DISP subsystem.
There is only one OVL engine in MT2701.
