    description:
      Configure the polarity of the PWRONx# signals. When this is present, the
      PWRONx# pins are active high and their internal pull-down resistors are
      disabled. When this is absent, the PWRONx# pins are active low (default)
      and their internal pull-down resistors are enabled.
