Merge tag 'nfc-next-4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
