+* Toshiba TC358746 Parallel to MIPI CSI2-TX or MIPI CSI2-RX to Parallel Bridge
+
+The Toshiba TC358746 is a bridge that converts a Parallel-in stream to MIPI 
CSI-2 TX
+or a MIPI CSI-2 RX stream into a Parallel-out. It is programmable through I2C.
+
+Required Properties:
+
+- compatible: should be "toshiba,tc358746"
+- reg: should be <0x0e>
+- clocks: should contain a phandle link to the reference clock source
+- clock-names: the clock input is named "refclk".
+
+Optional Properties:
+
+- reset-gpios: gpio phandle GPIO connected to the reset pin
+
+Parallel Endpoint:
+
+Required Properties:
+
+- reg: should be <0>
+- bus-width: the data bus width e.g. <8> for eight bit bus, or <16>
+            for sixteen bit wide bus.
+
+MIPI CSI-2 Endpoint:
+
+Required Properties:
+
+- reg: should be <1>
+- data-lanes: should be <1 2 3 4> for four-lane operation,
+             or <1 2> for two-lane operation
+- clock-lanes: should be <0>
+- link-frequencies: List of allowed link frequencies in Hz. Each frequency is
+                   expressed as a 64-bit big-endian integer. The frequency
+                   is half of the bps per lane due to DDR transmission.
+
+Optional Properties:
+
+- clock-noncontinuous: Presence of this boolean property decides whether the
+                      MIPI CSI-2 clock is continuous or non-continuous.
+
+For further information on the endpoint node properties, see
+Documentation/devicetree/bindings/media/video-interfaces.txt.
