====================
NFC 4.4 pull request

This is the NFC pull request for 4.4.

It's a bit bigger than usual, the 3 main culprits being:

- A new driver for Intel's Fields Peak NCI chipset. In order to
  support this chipset we had to export a few NCI routines and
  extend the driver NCI ops to not only support proprietary
  commands but also core ones.

- Support for vendor commands for both STM drivers, st-nci
  and st21nfca. Those vendor commands allow to run factory tests
  through the NFC netlink interface.

- New i2c and SPI support for the Marvell driver, together with
  firmware download support for this driver's core.

Besides that we also have:

- A few file renames in the STM drivers, to keep the naming
  consistent between drivers.

- Some improvements and fixes on the NCI HCI layer, mostly to
  properly reach a secure element over a legacy HCI link.

- A few fixes for the s3fwrn5 and trf7970a drivers.
