[PATCH 1/2] ARM: dts: gemini: ns2502: permit to use gigabit

From: Corentin Labbe
Date: Sat Jan 15 2022 - 05:05:10 EST


I believed that gigabit was not working due to some unknown missing GPIO.
In fact, gigabit worked when REALTEK_PHY was compiled out.
So the problem was due to PHY delay and we need to use rgmii-id.
