[PATCH v2 1/2] arm64: dt: imx93-tqma9352-mba93xxca: enable Open Drain for MDIO
From: Alexander Stein
Date: Thu Dec 05 2024 - 10:08:58 EST
From: Markus Niebel <Markus.Niebel@xxxxxxxxxxxxxxx>
The board has a pull-up resistor for MDIO pin per PHY design guide.
When MDIO is idle, it needs to be high and open drain is better
to be used here for power saving.
