This patchset adds the GPIO lines names to describe the /real/ GPIO usage on
the Odroid-C2 board. These names are useful to have a clear and human readable
decription of the line usage.
The second patch is not specifically tied to the names but was found using
these descriptions since they did not match.
Here is an extract of the GPIO debugfs output :
# cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-13, parent: platform/c8100000.aobus:pinctrl@14, aobus-banks:

This patch describes the GPIO lines usage on the Odroid-C2 board.
This is useful in the debugfs gpio file and using the cdev gpio API.
