====================
NFC 4.12 pull request

This is the NFC pull request for 4.12. We have:

- Improvements for the pn533 command queue handling and device
  registration order.
- Removal of platform data for the pn544 and st21nfca drivers.
- Additional device tree options to support more trf7970a hardware options.
- Support for Sony's RC-S380P through the port100 driver.
- Removal of the obsolte nfcwilink driver.
- Headers inclusion cleanups (miscdevice.h, unaligned.h) for many drivers.
====================
