[PATCH v2] dt-bindings: display/bridge: tc358764: Convert to YAML binding

[AngeloGioacchino Del Regno]

Convert the Toshiba TC358764 txt documentation to YAML.

Note: dtbs_check on exynos5250-arndale.dts will give some warnings after
      applying this patch: since the preferred way is to have 'ports',
      this warning was ignored.
      I have no Exynos5250 board, so the dts fix is left to someone who
      is able to test on the real hw.

-TC358764 MIPI-DSI to LVDS panel bridge
-
-Required properties:
-  - compatible: "toshiba,tc358764"
-  - reg: the virtual channel number of a DSI peripheral
-  - vddc-supply: core voltage supply, 1.2V
-  - vddio-supply: I/O voltage supply, 1.8V or 3.3V
-  - vddlvds-supply: LVDS1/2 voltage supply, 3.3V
-  - reset-gpios: a GPIO spec for the reset pin
-
-The device node can contain following 'port' child nodes,
-according to the OF graph bindings defined in [1]:
-  0: DSI Input, not required, if the bridge is DSI controlled
-  1: LVDS Output, mandatory
-
-[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
-
-Example:
-
-	bridge@0 {
-		reg = <0>;
-		compatible = "toshiba,tc358764";
-		vddc-supply = <&vcc_1v2_reg>;
-		vddio-supply = <&vcc_1v8_reg>;
-		vddlvds-supply = <&vcc_3v3_reg>;
-		reset-gpios = <&gpd1 6 GPIO_ACTIVE_LOW>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		port@1 {
-			reg = <1>;
-			lvds_ep: endpoint {
-				remote-endpoint = <&panel_ep>;
-			};
-		};
-	};
