LoongArch: dts: loongson-2k1000: Fix i2c-gpio node names2026-01-17T02:56:53+00:00Binbin Zhouzhoubinbin@loongson.cn2026-01-17T02:56:53+00:00urn:sha1:14ea5a3625881d79f75418c66e3a7d98db8518e1
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.

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: Describe PCI sideband IRQ through interrupt-extended2026-01-17T02:56:52+00:00Yao Zime@ziyao.cc2026-01-17T02:56:52+00:00urn:sha1:762cf75bec2ad9d17899087899a34336b1757238
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.
