+* 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.
+
+Example:
+
+&i2c {
+ tc358746: tc358746@0e {
+ reg = <0x0e>;
+ compatible = "toshiba,tc358746";
+ pinctrl-names = "default";
+ clocks = <&clk_cam_ref>;
+ clock-names = "refclk";
+ reset-gpios = <&gpio3 2 GPIO_ACTIVE_LOW>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ tc358746_parallel_in: endpoint {
+ bus-width = <8>;
+ remote-endpoint = <&micron_parallel_out>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ tc358746_mipi2_out: endpoint {
+ remote-endpoint = <&mipi_csi2_in>;
+ data-lanes = <1 2>;
+ clock-lanes = <0>;
+ clock-noncontinuous;
+ link-frequencies = /bits/ 64 <216000000>;
+ };
+ };
+ };
+};
