+Cadence MIPI-CSI2 RX controller
+===============================
+
+The Cadence MIPI-CSI2 RX controller is a CSI-2 bridge supporting up to 4 CSI
+lanes in input, and 4 different pixel streams in output.
+
+Required properties:
+ - compatible: must be set to "cdns,csi2rx" and an SoC-specific compatible
+ - reg: base address and size of the memory mapped region
+ - clocks: phandles to the clocks driving the controller
+ - clock-names: must contain:
+ * sys_clk: main clock
+ * p_clk: register bank clock
+ * pixel_if[0-3]_clk: pixel stream output clock, one for each stream
+ implemented in hardware, between 0 and 3
+
+Optional properties:
+ - phys: phandle to the external D-PHY, phy-names must be provided
+ - phy-names: must contain "dphy", if the implementation uses an
+ external D-PHY
+
+Required subnodes:
+ - ports: A ports node with one port child node per device input and output
+ port, in accordance with the video interface bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ port nodes are numbered as follows:
+
+ Port Description
+ -----------------------------
+ 0 CSI-2 input
+ 1 Stream 0 output
+ 2 Stream 1 output
+ 3 Stream 2 output
+ 4 Stream 3 output
+
+ The stream output port nodes are optional if they are not
+ connected to anything at the hardware level or implemented
+ in the design.Since there is only one endpoint per port,
+ the endpoints are not numbered.
+
+
+Example:
+
