Samuel Ortiz <sameo@linux.intel.com> says:
"NFC: 3.18 pull request
This is the NFC pull request for 3.18.
We've had major updates for TI and ST Microelectronics drivers:
For TI's trf7970a driver:
- Target mode support for trf7970a
- Suspend/resume support for trf7970a
- DT properties additions to handle different quirks
- A bunch of fixes for smartphone IOP related issues
For ST Microelectronics' ST21NFCA and ST21NFCB drivers:
- ISO15693 support for st21nfcb
- checkpatch and sparse related warning fixes
- Code cleanups and a few minor fixes
Finally, Marvell add ISO15693 support to the NCI stack, together with a
couple of NCI fixes."
