The GPIOD API handles GPIO active assertion levels as defined by the DT binding. So the phy-reset-active-high and/or phy-reset-active-low property is not needed when using the GPIOD API - just define GPIO_ACTIVE_LOW or GPIO_ACTIVE_HIGH as required for the board and the GPIOD API will handle active assert/deassert level as needed. -- Regards, George
