+Description: read/write
Here it should be 'read only', to be fixed.
+ Space separated list of LEDs available for flash strobe
+ synchronization, displayed in the format:
+
+ led1_id.led1_name led2_id.led2_name led3_id.led3_name etc.
Multiple values per file, with all the problems we had in /proc. I
assume led_id is an integer?
Yes.
What prevents space or dot in led name?
Space can be forbidden by defining naming convention. The name comes
from the DT binding 'label' property and I don't see any problem in
forbidding space in it.
A dot in the name does not introduce parsing problems - simply the first
dot after digits separates led id from led name.
