Hi, the leds-ns2 kernel driver has allows 3 modes for a LED: OFF, ON and blinking on SATA activity This third mode is activated via another sysfs file in the LED device sysfs directory: /sys/class/leds/<LED>/sata. Since we now support LED private HW triggers, it would be better if this was rewritten to use this new API. The question is how many people use this mode and may complain if we change this sysfs ABI? Another question is whether the LED supports another HW blinking mode, or just SATA? How is this wired on the board? Marek
