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 <zhoubinbin@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2026-01-23T10:18:48+00:00 Binbin Zhou zhoubinbin@loongson.cn 2026-01-17T02:56:53+00:00 urn:sha1:4df476a33687ba42bead19106d095d847636dd02 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.

So we need the PHY to insert internal delays for both transmit and receive data lines from/to the PHY device. Fix this by changing the "phy-mode" from "rgmii" to "rgmii-id" in dts.
