-* Toshiba TC358743 HDMI-RX to MIPI CSI2-TX Bridge
-
-The Toshiba TC358743 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts
-a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C.
-
-Required Properties:
-
-- compatible: value should be "toshiba,tc358743"
-- clocks, clock-names: should contain a phandle link to the reference clock
-		       source, the clock input is named "refclk".
-
-Optional Properties:
-
-- reset-gpios: gpio phandle GPIO connected to the reset pin
-- interrupts: GPIO connected to the interrupt pin
-- data-lanes: should be <1 2 3 4> for four-lane operation,
-	      or <1 2> for two-lane operation
-- clock-lanes: should be <0>
-- clock-noncontinuous: Presence of this boolean property decides whether the
-		       MIPI CSI-2 clock is continuous or non-continuous.
-- 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.
-
-For further information on the MIPI CSI-2 endpoint node properties, see
-Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Example:
-
-	tc358743@f {
-		compatible = "toshiba,tc358743";
-		reg = <0x0f>;
-		clocks = <&hdmi_osc>;
-		clock-names = "refclk";
-		reset-gpios = <&gpio6 9 GPIO_ACTIVE_LOW>;
-		interrupt-parent = <&gpio2>;
-		interrupts = <5 IRQ_TYPE_LEVEL_HIGH>;
-
-		port {
-			tc358743_out: endpoint {
-				remote-endpoint = <&mipi_csi2_in>;
-				data-lanes = <1 2 3 4>;
-				clock-lanes = <0>;
-				clock-noncontinuous;
-				link-frequencies = /bits/ 64 <297000000>;
-			};
-		};
-	};
