Dear Linux folks,


Starting Manjaro ARM on a Pine64 Pinebook Pro, Linux 6.0.7 logs:

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 */
<0x0 0xfff00000 0 0x10000>, /* GICC */
<0x0 0xfff10000 0 0x10000>, /* GICH */
<0x0 0xfff20000 0 0x10000>; /* GICV */
interrupts = <GIC_PPI 9 IRQ_TYPE_LEVEL_HIGH 0>;
its: interrupt-controller@fee20000 {
compatible = "arm,gic-v3-its";
msi-controller;
#msi-cells = <1>;
reg = <0x0 0xfee20000 0x0 0x20000>;
};

ppi-partitions {
ppi_cluster0: interrupt-partition-0 {
affinity = <&cpu_l0 &cpu_l1 &cpu_l2 &cpu_l3>;
};

ppi_cluster1: interrupt-partition-1 {
affinity = <&cpu_b0 &cpu_b1>;
};
};
};
```


Kind regards,
