Hi all,
I have try to use leds-regulator to implement my case, most works. But the only
thing doesn't work is the enable-gpio. In my case, we don't have a real enable
gpio, so when we set LED_OFF, it could not off the LED as we expected.
So I think I will back to the new multi LED driver, but make it more generic.
Best Regards,
Hermes
