RZ/G2L RGB HAS NO CLOCK OR SIGNALS

Dear Team,

             We using a custom board based on RZ/G2L and RGB to LVDS connected by a SN75LVDS83ADGGR flat transmitter. We have written the dtsi code for rgb according to this renesas website, ie https://renesas.info/wiki/RZ-G/RZG_DeviceTree#Display . We have connected 4 channel 24 bit lvds and the device tree as follows:

rgb-dummy {
		compatible = "renesas,rgb-dummy";
		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			port@0 {
				reg = <0>;
				rgb_in: endpoint {
					remote-endpoint = <&du_out_rgb>;
					};
				};
				port@1 {
					reg = <1>;
						rgb_out: endpoint {
							remote-endpoint = <&panel_in>;
						};
				};
			};
		};
panel {
	compatible = "dlc,dlc1010gig";/*edited*/
	power-supply = <&vcc_lcd_reg>;
	backlight = <&backlight>;
	status = "okay";
	port {
		panel_in: endpoint {
			remote-endpoint = <&rgb_out>;
		};
	};
	};
	};&pinctrl {
        du_pins: du {
		data {
			pinmux = <RZG2L_PORT_PINMUX(7,  2, 1)>,<RZG2L_PORT_PINMUX(8,  0, 1)>,<RZG2L_PORT_PINMUX(8,  1, 1)>,<RZG2L_PORT_PINMUX(8,  2, 1)>,<RZG2L_PORT_PINMUX(9,  0, 1)>,<RZG2L_PORT_PINMUX(9,  1, 1)>,<RZG2L_PORT_PINMUX(10, 0, 1)>,<RZG2L_PORT_PINMUX(10, 1, 1)>,<RZG2L_PORT_PINMUX(11, 0, 1)>,<RZG2L_PORT_PINMUX(11, 1, 1)>,<RZG2L_PORT_PINMUX(12, 0, 1)>,<RZG2L_PORT_PINMUX(12, 1, 1)>,<RZG2L_PORT_PINMUX(13, 0, 1)>,<RZG2L_PORT_PINMUX(13, 1, 1)>,<RZG2L_PORT_PINMUX(13, 2, 1)>,<RZG2L_PORT_PINMUX(14, 0, 1)>,<RZG2L_PORT_PINMUX(14, 1, 1)>,<RZG2L_PORT_PINMUX(15, 0, 1)>,<RZG2L_PORT_PINMUX(15, 1, 1)>,<RZG2L_PORT_PINMUX(16, 0, 1)>,<RZG2L_PORT_PINMUX(16, 1, 1)>,<RZG2L_PORT_PINMUX(17, 0, 1)>,<RZG2L_PORT_PINMUX(17, 1, 1)>,<RZG2L_PORT_PINMUX(17, 2, 1)>;
		};

		sync {
			pinmux = <RZG2L_PORT_PINMUX(6, 1, 1)>, /* HSYNC */<RZG2L_PORT_PINMUX(7, 0, 1)>; /* VSYNC */
		};

		de {
			pinmux = <RZG2L_PORT_PINMUX(7, 1, 1)>; /* DE */
		};
		clk {
			pinmux = <RZG2L_PORT_PINMUX(6, 0, 1)>; /* CLK */
		};
	};
};	

1. There is no error showing in the kernel. But it is not detecting the display as there is no /dev/fb0.

2. There is no clock or signals from RGB.

I am attaching a our RGB to LVDS schematic part for your reference.

Can you please suggest any software changes ? Is there any change in panel-simple.c code for  display timings and panel info?. Please help.
