This patch adds the gpio.c and gpio.h files, which support access to GPIO Controller (non-legacy) configuration register through a function interface. It doesn't add interrupt support due to pinmux reasons. On Galileo Gen 2 we need to configure a pin as input/interrupt using pinmux and this can only be achieved through I2C. There's one pin exported by default as GPIO output and we used this one to test this driver. In the future, we plan to add an I2C driver and a pinmux configuration driver in order to solve this kind of problems.
The Contiki Operating System
Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.
Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
