Merge tag 'nfc-next-3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz <sameo@linux.intel.com> says:
"This is the first NFC pull request for 3.14
It includes:
* A new NFC driver for Marvell's 8897, and a few NCI fixes and
improvements needed to support this chipset.
* An LLCP fix for how we were setting the default MIU on a p2p link. If
there is no explicit MIU extension announced at connection time, we
must use the default one and not the one announced at LLCP link
establishement time.
* A pn544 EEPROM config update. Some of the currently EEPROM configured
values are overwriting the firmware ones while other should not be set
by the driver itself.
* Some NFC digital stack fixes and improvements. Asynchronous functions
are better documented, RF technologies and CRC functions are set upon
PSL_REQ reception, and a few minor bugs are fixed.
* Minor and miscelaneous pn533, mei_phy and port100 fixes."
