Hi Rob, Mark,
Are there any remaining technical issues with this
binding doc? At this point an Ack from you is the only
thing holding up merge of the imx-media driver.
Note that the Synopsys core in the i.MX6 is a differently configured
Synopsys core from the core as described in the bindings at [1].
Russell King provided more information on the differences between these
cores at [2]. They are essentially different devices.
So perhaps the "snps,dw-mipi-csi2" compatibility needs to be removed
from this binding, for now, until this driver is moved to drivers/media/
and is made compatible with other MIPI CSI-2 Synopsys cores with
different configurations.

+Freescale i.MX Media Video Device
+=================================
+
+Video Media Controller node
+---------------------------
+
+This is the media controller node for video capture support. It is a
+virtual device that lists the camera serial interface nodes that the
+media device will control.
+
+Required properties:
+- compatible : "fsl,imx-capture-subsystem";
+- ports : Should contain a list of phandles pointing to camera
+ sensor interface ports of IPU devices
+
+example:
+
+capture-subsystem {
+ compatible = "fsl,imx-capture-subsystem";
+ ports = <&ipu1_csi0>, <&ipu1_csi1>;
+};
+
+
+mipi_csi2 node
+--------------
+
+This is the device node for the MIPI CSI-2 Receiver, required for MIPI
+CSI-2 sensors.
+
+Required properties:
+- compatible : "fsl,imx6-mipi-csi2", "snps,dw-mipi-csi2";
+- reg : physical base address and length of the register set;
+- clocks : the MIPI CSI-2 receiver requires three clocks: hsi_tx
+ (the D-PHY clock), video_27m (D-PHY PLL reference
+ clock), and eim_podf;
+- clock-names : must contain "dphy", "ref", "pix";
+- port@* : five port nodes must exist, containing endpoints
+ connecting to the source and sink devices according to
+ of_graph bindings. The first port is an input port,
+ connecting with a MIPI CSI-2 source, and ports 1
+ through 4 are output ports connecting with parallel
+ bus sink endpoint nodes and correspond to the four
+ MIPI CSI-2 virtual channel outputs.
+
+Optional properties:
+- interrupts : must contain two level-triggered interrupts,
+ in order: 100 and 101;
