So ... it was chosen to be compatible with linux gpio api, that's what I 
understood ... so I grepped the kernel source:

linux-2.6# git grep name_to_gpio drivers/gpio/
linux-2.6# git grep name_to_gpio include/
linux-2.6# git grep gpio_to_name include/
linux-2.6# git grep gpio_to_name drivers/gpio/

Nothing.

[...]
