GPIO

I've gathered some of GPIO functions:

Tested by telnet: gpio disable 5 #internet blue on gpio enable 6 #internet orange off

gpio disable 6 #internet orange on gpio enable 5 #internet blue off

gpio disable 8 #modem orange on gpio enable 8 #modem orange off

gpio disable 11 #modem blue on gpio enable 11 #modem blue off

gpio disable 9 #router blue on gpio enable 9 #router blue off

gpio pool 10 pressed = 00 unpressed = 01 gpio disable 10 #factory reset
 * 1) Long press resset button

gpio enable 12 #security orange off gpio disable 12 #security orange on

gpio enable 13 #security blue off gpio disable 13 #security blue on

gpio enable 22 #storage orange off gpio disable 22 #storage orange on

gpio enable 23 #storage blue off gpio disable 23 #storage blue on

gpio pool 0 pressed = 00 unpressed = 01
 * 1) wps button

Gathered from OpenWrt:
 * wired/wireless leds are controlled via bit shift register sitting on gpio pins 14 (ctl) and 4 (clk)
 * speed leds are controlled via bit shift register sitting on pins 17 (ctl) and 18 (clk)

Some notes:
 * restore config function doesn't work properly, the router get stucked.
 * PPPoE doesn't work with preselected want port, bridge port must be selected for wan, br0
 * current firmware level is more to instable to use it for a long period of time, if there will be any new releases and if the time permits I'll test them.
