Subject: [RFC PATCH v2 4/4] ARM: dts: imx6qdl: Add ports and endpoints to IPU DIs
Date: Tue, 11 Feb 2014 12:45:44 +0100 [thread overview]
Message-ID: <1392119144-27868-5-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1392119144-27868-1-git-send-email-p.zabel@pengutronix.de>
This connects the IPU and display encoder (HDMI, LVDS, MIPI)
device tree nodes using the bindings described in
Documentation/devicetree/bindings/media/video-interfaces.txt
The IPU ports correspond to the two display interfaces. The
order of endpoints in the ports is arbitrary.
Each encoder with an associated input multiplexer has multiple
input ports in the device tree. The order and reg property of
the ports must correspond to the multiplexer input order.
