All rest looks good, nice patch! Best regards, Krzysztof

The reset GPIO was marked active-high, which is against what's specified in the documentation. Mark the reset GPIO as active-low. With this change, Bluetooth can now be used on the i9100. Also switch away from using the deprecated 'host-wakeup-gpios' property, and use a 'host-wakeup' interrupt instead.
