Ok, have finished another project and could check:

root at letux:~# ls -l /sys/devices/system/clocksource/clocksource0/                    
total 0
-r--r--r-- 1 root root 4096 Nov  3 17:18 available_clocksource
-rw-r--r-- 1 root root 4096 Nov  3 17:18 current_clocksource
drwxr-xr-x 2 root root    0 Nov  3 17:18 power
lrwxrwxrwx 1 root root    0 Nov  3 17:16 subsystem -> ../../../../bus/clocksource
-rw-r--r-- 1 root root 4096 Nov  3 17:16 uevent
--w------- 1 root root 4096 Nov  3 17:18 unbind_clocksource
root at letux:~# cat /sys/devices/system/clocksource/clocksource0/*
ingenic-timer 
ingenic-timer
cat: /sys/devices/system/clocksource/clocksource0/power: Is a directory
cat: /sys/devices/system/clocksource/clocksource0/subsystem: Is a directory
cat: /sys/devices/system/clocksource/clocksource0/unbind_clocksource: Permission denied
root at letux:~#

Does that help?

BR,
Nikolaus
