Hrm. In that case these rise times are very large - I'd expect them to cause issues with led_set_blink() users? Though actually I suspect the solution here is to pull these out into the framework later; we can probably simulate reasonably in software with a lot of brightness variable LEDs. > > > +What: /sys/class/leds/<led>/max_current > > Shouldn't this be set by platform data, the maximum current you can push > > through the LEDs seems like a board dependant thing which won't change > > dynamically at runtime.

I'd strongly suggest removing this for mainline. If it's present it should at least be limited to the maximum specified in platform data (just for safety if nothing else).
