commit e65df3f77ecd59d3a8647d19df82b22a6ce210a9 upstream.
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)

LoongArch: dts: loongson-2k1000: Fix i2c-gpio node names2026-01-23T10:21:32+00:00Binbin Zhouzhoubinbin@loongson.cn2026-01-17T02:56:53+00:00urn:sha1:8a692ca14f4ca6b6f99fabe9bb186052697a9655
commit 14ea5a3625881d79f75418c66e3a7d98db8518e1 upstream.
The binding wants the node to be named "i2c-number", but those are named
"i2c-gpio-number" instead.
Thus rename those to i2c-0, i2c-1 to adhere to the binding and suppress
dtbs_check warnings.

LoongArch: dts: Describe PCI sideband IRQ through interrupt-extended2026-01-23T10:21:30+00:00Yao Zime@ziyao.cc2026-01-17T02:56:52+00:00urn:sha1:c1cc55ea5e956f60ff54a03c9712285f82737065
commit 762cf75bec2ad9d17899087899a34336b1757238 upstream.
SoC integrated peripherals on LS2K1000 and LS2K2000 could be discovered
as PCI devices, but require sideband interrupts to function, which are
previously described by interrupts and interrupt-parent properties.
However, pci/pci-device.yaml allows interrupts property to only specify
PCI INTx interrupts, not sideband ones. Convert these devices to use
interrupt-extended property, which describes sideband interrupts used by
PCI devices since dt-schema commit e6ea659d2baa ("schemas: pci-device:
Allow interrupts-extended for sideband interrupts"), eliminating
dtbs_check warnings.
