1 Driver a GPIO line that can be used to turn the power off.
3 The driver supports both level triggered and edge triggered power off.
5 install a handler to power off the system. If the optional properties
9 When the power-off handler is called, the gpio is configured as an
10 output, and drive active, so triggering a level triggered power off
11 condition. This will also cause an inactive->active edge condition, so
12 triggering positive edge triggered power off. After a delay of 100ms,
13 the GPIO is set to inactive, thus causing an active->inactive edge,
14 triggering negative edge triggered power off. After another 100ms
15 delay the GPIO is driver active again. If the power is still on and
16 the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
