====================
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.

Required properties:

- compatible: Should be "mrvl,nfc-uart".



Optional SoC specific properties:

- pinctrl-names: Contains only one value - "default".

- pintctrl-0: Specifies the pin control groups used for this controller.

- reset-n-io: Output GPIO pin used to reset the chip (active low).

- hci-muxed: Specifies that the chip is muxing NCI over HCI frames.



Optional UART-based chip specific properties:

- flow-control: Specifies that the chip is using RTS/CTS.

- break-control: Specifies that the chip needs specific break management.



Example (for ARM-based BeagleBoard Black with 88W8887 on UART5):



&uart5 {

	status = "okay";



	nfcmrvluart: nfcmrvluart@5 {

		compatible = "mrvl,nfc-uart";



		reset-n-io = <&gpio3 16 0>;



		hci-muxed;

		flow-control;

        }
