The drivers are already included in the kernel, to activate them check:
- for the 3.12 kernel https://www.hifiberry.com/build/documentation/hifiberry-software-configuration/
- for the 4.x kernel https://www.hifiberry.com/build/documentation/configuring-linux-3-18-x/.

GPIO 2-3 (pins 3 and 5) are used for configuration - I2C GPIOs 18-21 (pins 12, 35, 38 and 40) are used for the sound interface - I2S
