Adafruit-blinka

**This release represents a potentially breaking change for SPI on BeagleBone boards**

The port numbering has changed to use spidev0 and spidev1 instead of spidev1 and spidev2 because this is the what BeagleBoard will be using going forward. It is recommended to update your software and/or make any port numbering changes.

To use in CPython, `pip3 install adafruit-blinka`.
