Merge tag 'nfc-next-4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
