I found a corresponding definition in the devicetree `arch/arm64/boot/dts/rockchip/rk3399.dtsi`:

```
        gic: interrupt-controller@fee00000 {
                compatible = "arm,gic-v3";
                #interrupt-cells = <4>;
                #address-cells = <2>;
                #size-cells = <2>;
                ranges;
                interrupt-controller;

                reg = <0x0 0xfee00000 0 0x10000>, /* GICD */
                      <0x0 0xfef00000 0 0xc0000>, /* GICR */

                interrupts = <GIC_PPI 9 IRQ_TYPE_LEVEL_HIGH 0>;
                its: interrupt-controller@fee20000 {

                        msi-controller;
                        #msi-cells = <1>;
                        reg = <0x0 0xfee20000 0x0 0x20000>;
