Yeah, its 0x0a here.  If I set 0x140 I conflict with pin 7:

gpio0: <Atheros AR71XX GPIO driver> on apb0
gpio0: [GIANT-LOCKED]
gpio0: function_set: 0x0
gpio0: function_clear: 0x0
gpio0: gpio pinmask=0x9ff
gpioc0: <GPIO controller> on gpio0
gpiobus0: <GPIO bus> on gpio0
gpioiic0: warning: pin 6 is already mapped
gpioled0: <GPIO led> at pin(s) 0 on gpiobus0
gpioled1: <GPIO led> at pin(s) 1 on gpiobus0
gpioled2: <GPIO led> at pin(s) 2 on gpiobus0
gpioled3: <GPIO led> at pin(s) 4 on gpiobus0
gpioled4: <GPIO led> at pin(s) 6 on gpiobus0
gpioled5: <GPIO led> at pin(s) 11 on gpiobus0
