display LCD_RST schematic vs dt-overlay #22

In the latest schematic (v2.3) the !RST pin of the display LCD_RST is connected to GPIO6 of the CM4.

looking at the dt-overlay source cutiepi-panel-overlay.dts, I could not find where the GPIO6 as !RST is declared.

the only part where I can see something related to the display rst is this:

reset-gpios = <&gpio 20 0>;

but it looks like &gpio is the number 12, used for backlight control

fragment@1 {
        target = <&gpio>;
        __overlay__ {
            pwm_pins: pwm_pins {
                brcm,pins = <12>;
                brcm,function = <4>; // ALT0
            };
        };
    };

could you please clarify?
