Without the IRQF_ONESHOT flag in devm_request_threaded_irq() call I get
following error:
genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 56
gpio-keys gpio-keys: failed to request irq:56 for gpio:20
>From kernel/irq/manage.c:
The interrupt was requested with handler = NULL, so we use the default
primary handler for it. But it does not have the oneshot flag set. In
combination with level interrupts this is deadly, because the default
primary handler just wakes the thread, then the irq lines is reenabled,
but the device still has the level irq asserted. Rinse and repeat....
While this works for edge type interrupts, we play it safe and reject
unconditionally because we can't say for sure which type this interrupt
really has. The type flags are unreliable as the underlying chip
implementation can override them.

It was noticed that the system can hang during the reboot before the kernel
actually triggers the system reset and before all processes are stopped. The
watchdog didn't automatically restart the system because the om-watchdog
process was still running and triggering the hardware watchdog.
Instead the system should stop the watchdog during the shutdown to get the
benefit of an hardware reset in case of an software related problem. This stop
can be done quite easily with procd because it keeps track of its started
processes.

The Linux Distributed Switch Architecture drivers provide richer support than
the swconfig driver API in that each switch port gets its own interface which
allows protocols such as STP, LLDP, 802.1x etc.

Many gpio controllers 'cansleep' due to the fact that they are behind busses
e.g. i2c etc.
Using threaded irq's allows for 'sleep-able' gpio's to be used.
