The VGA overlay does not drive this signal, leaving the DAC disabled. The monitor receives the sync signals but displays a black image. On the Iris carrier board, the DAC power-save input is pulled high so the missing GPIO configuration does not prevent the VGA output from working. Add the pinctrl configuration and an active-high enable GPIO to the VGA bridge so that the simple-bridge driver takes the DAC out of power-save when enabling the output.
