====================
NFC 4.13 pull request

This is the NFC pull requesy for 4.13. We have:

- A conversion to unified device and GPIO APIs for the
  fdp, pn544, and st{21,-nci} drivers.
- A fix for NFC device IDs allocation.
- A fix for the nfcmrvl driver firmware download mechanism.
- A trf7970a DT and GPIO cleanup and clock setting fix.
- A few fixes for potential overflows in the digital and LLCP code.
