if the label is >=GPIO_NAME_SIZE, the result will not be NUL terminated.  i'd 
suggest you add something like this to after the strncpy call:
	gpio_names[gp].name[GPIO_NAME_SIZE - 1] = '\0';

could be written as !!(val >> GPIO_BIT(gp)), but up to you, or see how the 
code size works out

otherwise, looks fine.  not that i looked too closely as i dont know anything 
about Tegra2 parts.
