| Hi Andy.
| Being able to know the cause of a wakeup sounds really useful!
| Are the codes you're reporting described more fully somewhere? I'd have
| no idea what "second" means, for example.
The lower case ones under PMU are PMU interrupt sources that are
"hidden" inside a single interrupt pin that reaches the CPU from the
PMU, they're documented in the pcf50633 datasheet you can hopefully
still get from here:
Only a very few of those are enabled for wake when
fix-reduce-wake-reasons-in-pcf50633.patch goes in stable:
~ - USB insertion
~ - USB removal
~ - RTC Alarm
~ - Power key pressed
~ - Power key pressed for 1s (hm oh well)
"second" is a 1s heartbeat interrupt you can enable, but it isn't used
for wake. I listed everything in case things accidentally get enabled
for wake in the future.
