Hi,
I have scanned through some of the led sysfs interfaces of my hardware
boards inside the /sys/class/leds and found these
brightness,
max_brightness
trigger
uevent
invert
sata

I want to know can we add our own custom sysfs interface ?
Does there exists a default list of interfaces provided by the led
class subsystem? like brightness, max_brightness,trigger,uevent ,etc??

Thanks in advance !

You can add custom sysfs attributes by initializing "groups" property
of struct led_classdev.
