linux-toradex.git/arch/mips/boot/dts, branch master Linux kernel for Apalis and Colibri modules MIPS: Loongson64: dts: fix phy-related definition of LS7A GMAC 2026-01-30T14:35:26+00:00 Icenowy Zheng zhengxingda@iscas.ac.cn 2026-01-02T15:52:43+00:00 e4ec36bf7bc7023e1d207b1277755b0da381f20f Currently the LS7A GMAC device tree node lacks a proper phy-handle property pointing to the PHY node. In addition, the phy-mode property specifies "rgmii" without any internal delay information, which means the board trace needs to add 2ns delay to the RGMII data lines; but that isn't known to happen on any Loongson board. The ACPI-based initialization codepath, which is used on LoongArch-based 3A5000 + 7A1000 hardwares, specifies "rgmii-id" phy mode, which should be the one we are using. Add the lacking phy-handle property and set proper phy-mode. Tested on a LS3A4000_7A1000_NUC_BOARD_V2.1 board with YT8521S PHY.
