That is very good to know, thank you! 
Well, yes I'd like to reimplement leds-gpio, I think. I guess a very simple LED driver would be a good learning experience for a beginner.
So, I have a question... When I write to "brightness" in /sys/devices/platform/leds/leds/pinephone:blue:user/ (Ubuntu Touch), then the brightness can be modified. Which, I assume, is a value that is used by the leds-gpio module and written in the corresponding memory mapped register. So, why is there no leds-gpio module present when I execute lsmod?
