3-color led too bright
Hi!
The indicator 3-color LED in mainline kernel seem to be a bit too bright. .. more bright to look at comfortably. I believe it is also brighter than in original maemo... I believe I've seen note somewhere that hardware may allow too much current to the 3-color led damaging hardware... but I can't find the link now.
Does anyone know more?
Thanks,
Pavel

Safe current limits for the leds are configured in the DTS (led-cur and max-cur) and can be checked in sysfs. I remember testing the safety limits when I added them to DT, but the driver has changed a bit since then.
