The problem is (probably, I haven't tested) that in
mach-kirkwood/board-dt.c, the of_platform_populate() function is called
after all the board-specific init. So all the devices described in the
DT, including GPIO banks, have not been registered yet. Most likely the
of_platform_populate() should come before the board specific inits.
Also there should probably be a gpio_request() before those
gpio_set_value().
Best regards,
Thomas
