-* STMicroelectronics : NFC Transceiver ST95HF
-
-ST NFC Transceiver is required to attach with SPI bus.
-ST95HF node should be defined in DT as SPI slave device of SPI
-master with which ST95HF transceiver is physically connected.
-The properties defined below are required to be the part of DT
-to include ST95HF transceiver into the platform.
-
-Required properties:
-===================
-- reg: Address of SPI slave "ST95HF transceiver" on SPI master bus.
-
-- compatible: should be "st,st95hf" for ST95HF NFC transceiver
-
-- spi-max-frequency: Max. operating SPI frequency for ST95HF
-	transceiver.
-
-- enable-gpio: GPIO line to enable ST95HF transceiver.
-
-- interrupts : Standard way to define ST95HF transceiver's out
-	interrupt.
-
-Optional property:
-=================
-- st95hfvin-supply : This is an optional property. It contains a
-	phandle to ST95HF transceiver's regulator supply node in DT.
-
-Example:
-=======
-spi@9840000 {
-	reg = <0x9840000 0x110>;
-	#address-cells = <1>;
-	#size-cells = <0>;
-	cs-gpios = <&pio0 4>;
-
-	st95hf@0{
-		reg = <0>;
-		compatible = "st,st95hf";
-		spi-max-frequency = <1000000>;
-		enable-gpio = <&pio4 0>;
-		interrupt-parent = <&pio0>;
-		interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
-	};
