Thanks to notro I solved the problem, changed the way the screen brightness was controlled.
Here is the configuration I have at the moment.

reset ---> PA7
led ---> PA6
dc ----> PA2

/dts-v1/;
/plugin/;

/ {
	compatible = "allwinner,sun8i-h3";

    fragment@0 {
        target-path = "/aliases";
        __overlay__ {
            spi1 = "/soc/spi@01c69000";
        };
    };

	fragment@1 {
		target = <&spi1>;
		__overlay__ {
			status = "okay";

			spidev@0{
				status = "disabled";
			};

			spidev@1{
				status = "disabled";
			};
		};
	};

	fragment@2 {
		target = <&pio>;
		__overlay__ {
			opiz_display_pins: opiz_display_pins {
                pins = "PA7", "PA2", "PA6";
                function = "gpio_out";
			};
		};
	};

	fragment@3 {
		target = <&spi1>;
		__overlay__ {
			/* needed to avoid dtc warning */
			#address-cells = <1>;
			#size-cells = <0>;
			opizdisplay: opiz-display@0{
				compatible = "ilitek,ili9341";
				reg = <0>;
				pinctrl-names = "default";
				pinctrl-0 = <&opiz_display_pins>;
				spi-max-frequency = <8000000>;
				rotate = <270>;
				bgr;
				fps = <30>;
				buswidth = <8>;
				reset-gpios = <&pio 0 7 1>;
				dc-gpios = <&pio 0 2 0>;
				led-gpios= <&pio 0 6 1>;
				debug = <3>;
				status="okay";
			};
		};
	};
	__overrides__ {
		speed =   <&opizdisplay>,"spi-max-frequency:0";
		rotate =  <&opizdisplay>,"rotate:0";
		fps =     <&opizdisplay>,"fps:0";
		debug =   <&opizdisplay>,"debug:0";
        };
};
