+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>;

+ port@0 {
+ reg = <0>;
+ panel0_in: endpoint {
+ remote-endpoint = <&dsi0_out>;
+ };
