Hello,
I'm trying to use 6lowpan on imote2 platform but with kernel 3.3-rc5 (latest 
git linux-zigbee devel )  I have this error at bootup:


...
[    0.265882] gpiochip_add: registered GPIOs 0 to 31 on device: gpio-0
[    0.269766] gpiochip_add: registered GPIOs 32 to 63 on device: gpio-1
[    0.273585] gpiochip_add: registered GPIOs 64 to 95 on device: gpio-2
[    0.278527] gpiochip_add: registered GPIOs 96 to 120 on device: gpio-3
[    0.312939] __mfp_validate: GPIO91 is invalid pin
[    0.313038] __mfp_validate: GPIO103 is invalid pin
[    0.313072] __mfp_validate: GPIO104 is invalid pin
[    0.313107] __mfp_validate: GPIO105 is invalid pin
[    0.313141] __mfp_validate: GPIO102 is invalid pin
[    0.313176] __mfp_validate: GPIO1 is invalid pin
...

Also, before this I add this 2 line in pxa27x.c file:

INIT_CLKREG(&clk_dummy, "pxa-gpio", NULL),
INIT_CLKREG(&clk_dummy, "pxa27x-rtc", NULL),

otherwise a -22 error result in gpio probing phase

So, cc2420 driver cannot be loaded (neither that use gpio, including leds)

is there any patch ?

thank you very much

Andrea
