-+Info: Drives a GPIO high or low on poweroff (including halt). Using this
-+ overlay interferes with the normal power-down sequence, preventing the
-+ kernel from resetting the SoC (a necessary step in a normal power-off
-+ or reboot). This also disables the ability to triger a boot by driving

-+ Users of this overlay are required to provide an external mechanism to
-+ switch off the power supply when signalled - failure to do so results
-+ in a kernel BUG, increased power consumption and undefined behaviour.
