[PATCH v2 4/6] dt-bindings: display: bridge: Add ICN6211 MIPI-DSI to RGB converter bridge

[Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx>]

ICN6211 is MIPI-DSI/RGB converter bridge from chipone.
It has a flexible configuration of MIPI DSI signal input
and produce RGB565, RGB666, RGB888 output format.

Add dt-bingings for it.

+Chipone ICN6211 MIPI-DSI to RGB Converter Bridge
+
+ICN6211 is MIPI-DSI/RGB converter bridge from chipone.
+It has a flexible configuration of MIPI DSI signal input
+and produce RGB565, RGB666, RGB888 output format.
+
+Required properties for RGB:
+- compatible: must be "chipone,icn6211"
+- reg: the virtual channel number of a DSI peripheral
+- reset-gpios: a GPIO phandle 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: RGB Output, mandatory
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+	panel {
+		compatible = "bananapi,s070wv20-ct16", "simple-panel";
+		enable-gpios = <&pio 1 7 GPIO_ACTIVE_HIGH>; /* LCD-PWR-EN: PB7 */
+		backlight = <&backlight>;
+
+		port {
+			panel_out_bridge: endpoint {
+				remote-endpoint = <&bridge_out_panel>;
+			};
+		};
+	};
+
+&dsi {
+	vcc-dsi-supply = <&reg_dcdc1>;		/* VCC-DSI */
+	status = "okay";
+
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		dsi_out: port@0 {
+			reg = <0>;
+
+			dsi_out_bridge: endpoint {
+				remote-endpoint = <&bridge_out_dsi>;
+			};
+		};
+	};
+
+	bridge@0 {
+		compatible = "chipone,icn6211";
+		reg = <0>;
+		reset-gpios = <&r_pio 0 5 GPIO_ACTIVE_HIGH>; /* LCD-RST: PL5 */
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			bridge_in: port@0 {
+				reg = <0>;
+
+				bridge_out_dsi: endpoint {
+					remote-endpoint = <&dsi_out_bridge>;
+				};
+			};
+
+			bridge_out: port@1 {
+				reg = <1>;
+
+				bridge_out_panel: endpoint {
+					remote-endpoint = <&panel_out_bridge>;
+				};
+			};
+		};
+	};
+};
