++Name:   pi3-act-led
++Info:   Pi3 uses a GPIO expander to drive the LEDs which can only be accessed
++        from the VPU. There is a special driver for this with a separate DT
++        node, which has the unfortunate consequence of breaking the
++        act_led_gpio and act_led_activelow dtparams.
++        This overlay changes the GPIO controller back to the standard one and
++        restores the dtparams.
