====================
NFC: 4.1 pull request

This is the NFC pull request for 4.1.

This is a shorter one than usual, as the Intel Field Peak NFC
driver could not make it in time.

We have:

- A new driver for NXP NCI based chipsets, like e.g. the NPC100 or
  the PN7150. It currently only supports an i2c physical layer, but
  could easily be extended to work on top of e.g. SPI.
  This driver also includes support for user space triggered firmware
  updates.

- A few minor st21nfc[ab] fixes, cleanups, and comments improvements.

- A pn533 error return fix.

- A few NFC related logs formatting cleanups.

* NXP Semiconductors NXP NCI NFC Controllers



Required properties:

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

- clock-frequency: I²C 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 chip

- 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 NPC100 NFC controller on I2C2):



&i2c2 {



	status = "okay";



	npc100: npc100@29 {



		compatible = "nxp,nxp-nci-i2c";



		reg = <0x29>;

		clock-frequency = <100000>;



		interrupt-parent = <&gpio1>;

		interrupts = <29 GPIO_ACTIVE_HIGH>;



		enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>;

		firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>;

	};

};
