From e65df3f77ecd59d3a8647d19df82b22a6ce210a9 Mon Sep 17 00:00:00 2001 From: Binbin Zhou Date: Sat, 17 Jan 2026 10:56:53 +0800 Subject: LoongArch: dts: loongson-2k2000: Add default interrupt controller address cells Add missing address-cells 0 to the Local I/O, Extend I/O and PCH-PIC Interrupt Controller node to silence W=1 warning: loongson-2k2000.dtsi:364.5-49: Warning (interrupt_map): /bus@10000000/pcie@1a000000/pcie@9,0:interrupt-map: Missing property '#address-cells' in node /bus@10000000/interrupt-controller@10000000, using 0 as fallback Value '0' is correct because: 1. The LIO/EIO/PCH interrupt controller does not have children, 2. interrupt-map property (in PCI node) consists of five components and the fourth component "parent unit address", which size is defined by '#address-cells' of the node pointed to by the interrupt-parent component, is not used (=0) Cc: stable@vger.kernel.org Signed-off-by: Binbin Zhou Signed-off-by: Huacai Chen --- arch/loongarch/boot/dts/loongson-2k2000.dtsi | 3 +++ 1 file changed, 3 insertions(+) diff --git a/arch/loongarch/boot/dts/loongson-2k2000.dtsi b/arch/loongarch/boot/dts/loongson-2k2000.dtsi index 87c45f1f7cc7..3678c084adf7 100644 --- a/arch/loongarch/boot/dts/loongson-2k2000.dtsi +++ b/arch/loongarch/boot/dts/loongson-2k2000.dtsi @@ -126,6 +126,7 @@ reg = <0x0 0x1fe01400 0x0 0x64>; interrupt-controller; + #address-cells = <0>; #interrupt-cells = <2>; interrupt-parent = <&cpuintc>; interrupts = <2>; @@ -140,6 +141,7 @@ compatible = "loongson,ls2k2000-eiointc"; reg = <0x0 0x1fe01600 0x0 0xea00>; interrupt-controller; + #address-cells = <0>; #interrupt-cells = <1>; interrupt-parent = <&cpuintc>; interrupts = <3>; @@ -149,6 +151,7 @@ compatible = "loongson,pch-pic-1.0"; reg = <0x0 0x10000000 0x0 0x400>; interrupt-controller; + #address-cells = <0>; #interrupt-cells = <2>; loongson,pic-base-vec = <0>; interrupt-parent = <&eiointc>; -- cgit v1.2.3
