This patch adds support to 4 user leds, wlan and bt led on board.

I'm not fond of the overly complicated names; and I think it should at
least be shortened to "db600c:...".

I agree, I will fix this in next version.

Tested this on my DB600c, seems to work, except the WiFi/BT triggers,
see comments below.

This should either be "phy0rx", "phy0tx", "phy0assoc" or "phy0radio". TX
does not seem to work, so this should be debugged; "assoc" is probably
the one that makes most sense.

Am ok, to change, did you get activity leds works with any of these 
strings with WLAN or BT?

phy0rx/tx seems to be bit more generic and atleast the name looks bit 
non-specific to wlan.

These names should be documented somewhere, Its very difficult to find 
which names to use unless you read the code.

It would be nice to just provide a phandle to the device which 
led-trigger should use, which makes it clear and explicit.

This should be "hci0-power".

Does this trigger work for you?
Name is bit misleading though.

Thanks,
