----------
**echo 255 > youku-yk1:blue:wan/brightness** turns led on and **echo 0 > youku-yk1:blue:wan/brightness** turns led off.
I also added (missing?) led configuration to **/etc/config/system**:


config led 'led_wan'
	option name 'wan'
	option sysfs 'youku-yk1:blue:wan'
	option trigger 'switch0'
	option port_mask '0x10'


and wan led blinks fine.

It is no problem to create PR on GitHub (or create patch) to me. The only problem is... description.
I do not understand what lack of __pinctrl-0 =  __ line really do.
