Hardware
NXP chip is used PN532/en. The chip is connected via SPI. GPIO is used as chip select.
Software
The chip is supported by the library libnfc, starting with release 1.7.0. Backport to Debian Wheezy: [1], by default in a standard way.
Work is done in userspace using spidev. By default when using the default dts file using device /dev/spidev1.4. Default config: [2].
