The commit was added to align with the existing convention of separating node addition and enabling logic in USB configurations. This approach is referenced from commits such as: https://lore.kernel.org/all/20250710-resends-july-exynos990-dt-v2-5-55033f73d1b0@mentallysanemainliners.org/ (local) https://lore.kernel.org/all/20240429-usb-dts-gs101-v2-2-7c1797c9db80@linaro.org/ (local) Please let me know if this commit to be merged in previous commit.
Best regards, Krzysztof
