And this is ungood:

pavel@duo:~/denx/active$ cat /sys/class/power_supply/BAT0/alarm 
2403000

What is it? Not exactly easy to guess, and not documented. 

pavel@duo:~$ grep alarm /data/l/linux-good/Documentation/ABI/*/*
/data/l/linux-good/Documentation/ABI/testing/sysfs-ptp:What:
/sys/class/ptp/ptpN/n_alarms
/data/l/linux-good/Documentation/ABI/testing/sysfs-ptp:		alarms
offer by the PTP hardware clock.
pavel@duo:~$ 

I wish files with physical values included units. alarm is probably in
uA, but it might be uW as well, and ... :-(.
