Merge tag 'nfc-next-4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says: ==================== NFC 4.2 pull request This is the NFC pull request for 4.2. - NCI drivers can now define their own handlers for processing proprietary NCI responses and notifications. - NFC vendors can use a dedicated netlink API to send their own proprietary commands, like e.g. all commands needed to implement vendor specific manufacturing tools. - A new generic NCI over UART driver against which any NCI chipset running on top of a serial interface can register. - The st21nfcb driver is renamed to st-nci as it can and will support most of ST Microelectronics NCI chipsets. - The st21nfcb driver can put its CLF in hibernate mode and save significant amount of power. - A few st21nfcb minor fixes. - The NXP NCI driver now supports ACPI enumeration. - The Marvell NCI driver now supports both USB and serial physical interfaces. - The Marvell NCI drivers also supports NCI frames being muxed over HCI. This is a setting that can be defined by a DT property. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
