Subject: [PATCH v2 2/2] arm64: dt: imx93-tqma9352-mba93xxla: enable Open Drain for MDIO
Date: Thu, 5 Dec 2024 16:07:29 +0100 [thread overview]
Message-ID: <20241205150730.3132807-2-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20241205150730.3132807-1-alexander.stein@ew.tq-group.com>
From: Markus Niebel <Markus.Niebel@ew.tq-group.com>
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.
