+Visionox model RM69299 DSI display driver
+
+The Visionox RM69299 is a generic display driver, currently only configured
+for use in the 1080p display on the Qualcomm SC7180 MTP board.
+
+Required properties:
+- compatible: should be "visionox,rm69299-1080p-display"
+- vdda-supply: phandle of the regulator that provides the supply voltage
+  Power IC supply
+- vdd3p3-supply: phandle of the regulator that provides the supply voltage
+  Power IC supply
+- reset-gpios: phandle of gpio for reset line
+  This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names
+  (active low)
+- mode-gpios: phandle of the gpio for choosing the mode of the display
+  for single DSI
+- ports: This device has one video port driven by one DSI. Their connections
+  are modeled using the OF graph bindings specified in
+  Documentation/devicetree/bindings/graph.txt.
+  - port@0: DSI input port driven by master DSI
+
+Example:
+
+	dsi@ae94000 {
+		panel@0 {
+			compatible = "visionox,rm69299-1080p-display";
+			reg = <0>;
+
+			vdda-supply = <&src_pp1800_l8c>;
+			vdd3p3-supply = <&src_pp2800_l18a>;
+
+			pinctrl-names = "default", "suspend";
+			pinctrl-0 = <&disp_pins_default>;
+			pinctrl-1 = <&disp_pins_default>;
+
+			reset-gpios = <&pm6150l_gpios 3 0>;
+
+			display-timings {
+				timing0: timing-0 {
+					/* originally
+					 * 268316160 Mhz,
+					 * but value below fits
+					 * better w/ downstream
+					 */
+					clock-frequency = <158695680>;
+					hactive = <1080>;
+					vactive = <2248>;
+					hfront-porch = <26>;
+					hback-porch = <36>;
+					hsync-len = <2>;
+					vfront-porch = <56>;
+					vback-porch = <4>;
+					vsync-len = <4>;
+				};
+			};
+
+			ports {
+				#address-cells = <1>;
+				#size-cells = <0>;
+				port@0 {
+					reg = <0>;
+					panel0_in: endpoint {
+						remote-endpoint = <&dsi0_out>;
+					};
+				};
+			};
+		};
+	};
