H A Dwkup-m3-ipc.yaml27 Support for VTT Toggle with GPIO pin
30 connected to the enable pin on the DDR VTT regulator. This allows the
80 ti,vtt-gpio-pin:
82 description: GPIO pin connected to enable pin on VTT regulator
129 ti,vtt-gpio-pin = <7>;
137 * On the AM437x-GP-EVM board, gpio5_7 is wired to enable pin of the DDR VTT
140 * state of the pin is configured for pull-down and thus the VTT regulator
142 * this method is an alternative to using the 'ti,vtt-gpio-pin' property.
