"NFC: 3.16: First pull request

This is the NFC pull request for 3.16. We have:

- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
  thus relies on the HCI stack. This submission provides support for tag
  redaer/writer mode (including Type 5) and device tree bindings.

- PM runtime support and a bunch of bug fixes for TI's trf7970a.

- Device tree support for NXP's pn544. Legacy platform data support is
  obviously kept intact.

- NFC Tag type 4B support to the NFC Digital stack.

- SOCK_RAW type support to the raw NFC socket, and allow NCI
  sniffing from that. This can be extended to report HCI frames and also
  proprietarry ones like e.g. the pn533 ones."

* NXP Semiconductors PN544 NFC Controller



Required properties:

- compatible: Should be "nxp,pn544-i2c".

- clock-frequency: IC work frequency.

- reg: address on the bus

- interrupt-parent: phandle for the interrupt gpio controller

- interrupts: GPIO interrupt to which the chip is connected

- enable-gpios: Output GPIO pin used for enabling/disabling the PN544

- firmware-gpios: Output GPIO pin used to enter firmware download mode



Optional SoC Specific Properties:

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

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



Example (for ARM-based BeagleBone with PN544 on I2C2):



&i2c2 {



	status = "okay";



	pn544: pn544@28 {



		compatible = "nxp,pn544-i2c";



		reg = <0x28>;

		clock-frequency = <400000>;



		interrupt-parent = <&gpio1>;

		interrupts = <17 GPIO_ACTIVE_HIGH>;



		enable-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;

		firmware-gpios = <&gpio3 19 GPIO_ACTIVE_HIGH>;

	};
