* STMicroelectronics SAS. ST NCI NFC Controller

Required properties:
- compatible: Should be "st,st21nfcb-i2c" or "st,st21nfcc-i2c".
- clock-frequency: I²C work frequency.
- reg: address on the bus
- interrupts: GPIO interrupt to which the chip is connected
- reset-gpios: Output GPIO pin used to reset the ST21NFCB

Optional SoC Specific Properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.
- ese-present: Specifies that an ese is physically connected to the nfc
controller.
- uicc-present: Specifies that the uicc swp signal can be physically
connected to the nfc controller.

Example (for ARM-based BeagleBoard xM with ST21NFCB on I2C2):

&i2c2 {

st21nfcb: st21nfcb@8 {

compatible = "st,st21nfcb-i2c";

reg = <0x08>;
		clock-frequency = <400000>;

interrupt-parent = <&gpio5>;
		interrupts = <2 IRQ_TYPE_LEVEL_HIGH>;

reset-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>;

ese-present;
		uicc-present;
	};
};
