6 handler. If the optional properties 'open-source' is not found, the GPIO line
11 priority order. The gpio is configured as an output, and driven active,
12 triggering a level triggered reset condition. This will also cause an
13 inactive->active edge condition, triggering positive edge triggered
14 reset. After a delay specified by active-delay, the GPIO is set to
15 inactive, thus causing an active->inactive edge, triggering negative edge
16 triggered reset. After a delay specified by inactive-delay, the GPIO
17 is driven active again. After a delay specified by wait-delay, the
