[PATCH v4 5/6] arm64: dts: qcom: qcs404: Inverse phy-mode for EVB-4000

From: Yijie Yang <hidden>
Date: 2025-08-19 06:37:08
Also in: linux-arm-kernel, linux-arm-msm, linux-devicetree, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

This board expects the MAC to add the delay. Set `phy-mode = "rgmii-id"`
in DTS to match upstream definition and work correctly with the updated
driver, which switches the semantic handling of 'rgmii' and 'rgmii-id'.

Breaking ABI compatibility is acceptable for this board, as it has no
known users or interest from any users.
