[PATCH 6/9] arm64: dts: imx8mm-beacon: Configure Ethernet reset and IRQ GPIO
From: Adam Ford
Date: Wed Apr 09 2025 - 21:01:21 EST
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.
