Original raspberry 7 inch display on Armbian

Could anyone help me to enable display with Armbian? I just can’t figure out why it doesn’t work. I don’t see the backlight turning on either. What do I have to change?

I have try to add the overlay but i think Is for 5.10 kernel…I’m not very experienced so I don’t know how I could do it

radxa/kernel/blob/linux-5.10-gen-rkr3.4/arch/arm64/boot/dts/rockchip/overlay/rock-4c-plus-raspi-7inch-touchscreen.dts

/dts-v1/;
/plugin/;

/ {
	metadata {
		title = "Enable Raspberry Pi 7-inch Touchscreen";
		compatible = "radxa,rock-4c-plus";
		category = "display";
		description = "Enable Raspberry Pi 7-inch Touchscreen";
	};

	fragment@0 {
		target = <&dsi>;

		__overlay__ {
			status = "okay";
			#address-cells = <1>;
			#size-cells = <0>;
			rockchip,lane-rate = <696>;
