BeagleBone Black RFID Adaptor Cape

Description
The RFID adaptor cape is an interface between the Beaglebone Black (BBB) and Texas Instrument's TRF7970ATB, (Multi-Protocol Fully Integrated 13.56-MHz RFID and NFC Transceiver) It allows users to have fully functional RFID and NFC capabilities on the BBB. The adaptor board also features four additional LEDs and a push button.

The communication between the BBB and the TB is via SPI. Since SPI pins are not automatically enabled on BBB, a device tree overlay is used to configure the pins properly for SPI use.
