I think using "lsgpio" fron tools/gpio/lsgpio.c is better to inspect
the available GPIOs.

If you haven't tested the GPIO tools, please try it out.

Unfortunately, this tool isn't very useful:

I believe you have to come up with a separate array of names and attach
that to the gpio_chip in msm_gpio_init() for the _gpio_ pins to have
names. The names we specify in the pin driver is only the name of the
pinctrl pin...
