[PATCH not-for-merge 3/3] arm: dts: k3-am625-beagleplay: Fix Ethernet PHY reset GPIO

Roger Quadros rogerq at kernel.org
Thu Apr 25 14:20:54 CEST 2024


Move GPIO pinmux to MDIO node. Add GB Ethernet reset GPIO.

Add PIN_INPUT to Fix SPE ethernet reset gpio so that
reading the GPIO can give correct status.
