Merge tag 'nfc-next-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says: ==================== NFC 4.5 pull request This is the first NFC pull request for 4.5 and it brings: - A new driver for the STMicroelectronics ST95HF NFC chipset. The ST95HF is an NFC digital transceiver with an embedded analog front-end and as such relies on the Linux NFC digital implementation. This is the 3rd user of the NFC digital stack. - ACPI support for the ST st-nci and st21nfca drivers. - A small improvement for the nfcsim driver, as we can now tune the Rx delay through sysfs. - A bunch of minor cleanups and small fixes from Christophe Ricard, for a few drivers and the NFC core code. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
