Subject: [PATCH 7/9] arm64: dts: imx8mn-beacon: Configure Ethernet reset and IRQ GPIO
Date: Wed, 9 Apr 2025 19:59:01 -0500 [thread overview]
Message-ID: <20250410005912.118732-7-aford173@gmail.com> (raw)
In-Reply-To: <20250410005912.118732-1-aford173@gmail.com>
The ethernet PHY setup assumes the bootloader will pull the PHY out
of reset,but it's not guaranteed. The PHY is also currently
setup to poll, because it does not configure the IRQ. Enable
both GPIO settings for better optimal ethernet performance.
