I'm really not sure about this one.

This is something that can easily be changed through sysfs, and it
will likely end up being a "war" on what trigger people want to use.

Hans, Chen-Yu, What's your view on this?

Thanks,
Maxime

I would prefer to not set any (default) led triggers in the dts
files for sunxi boards.

If so, then Ok, please ignore this patch.

Is there any way to set led triggers through cmdline instead of sysfs?

Unfortunately, I don't think there's any.
