| Series | [1/2] arm64: dt: imx93-tqma9352-mba93xxca: enable Open Drain for MDIO | expand |
> Subject: [PATCH 1/2] arm64: dt: imx93-tqma9352-mba93xxca: enable > Open Drain for MDIO > > From: Markus Niebel <Markus.Niebel@ew.tq-group.com> > > Follow suggestion from hardware team. This is a bit vague, my guess: 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.
