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>;
+ };
+ };
+ };
+ };
+};
