Subject: [PATCH v5 2/2] drm/fsl-dcu: add support for drm bridge
Date: Fri, 15 Jul 2016 14:53:38 +0800 [thread overview]
Message-ID: <1468565618-27124-2-git-send-email-meng.yi@nxp.com> (raw)
In-Reply-To: <1468565618-27124-1-git-send-email-meng.yi@nxp.com>
The current output code only supports connection to drm panels.
Add code to support drm bridge, to support connections to
external connectors.
