ARM: dts: am3517-evm: Enable Ethernet PHY Interrupt
The Ethernet PHY interrupt pin is routed to GPIO_58. Create a PHY node to configure this GPIO for the interrupt to avoid polling. Signed-off-by: Adam Ford <aford173@gmail.com> Message-ID: <20231005000402.50879-2-aford173@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
