1 * STMicroelectronics : NFC Transceiver ST95HF
2
3 ST NFC Transceiver is required to attach with SPI bus.
4 ST95HF node should be defined in DT as SPI slave device of SPI
5 master with which ST95HF transceiver is physically connected.
6 The properties defined below are required to be the part of DT
7 to include ST95HF transceiver into the platform.
8
9 Required properties:
10 ===================
11 - reg: Address of SPI slave "ST95HF transceiver" on SPI master bus.
12
13 - compatible: should be "st,st95hf" for ST95HF NFC transceiver
14
15 - spi-max-frequency: Max. operating SPI frequency for ST95HF
16 transceiver.
17
18 - enable-gpio: GPIO line to enable ST95HF transceiver.
19
20 - interrupts : Standard way to define ST95HF transceiver's out
21 interrupt.
22
23 Optional property:
24 =================
25 - st95hfvin-supply : This is an optional property. It contains a
26 phandle to ST95HF transceiver's regulator supply node in DT.
27
28 Example:
29 =======
30 spi@9840000 {
31 reg = <0x9840000 0x110>;
32 #address-cells = <1>;
33 #size-cells = <0>;
34 cs-gpios = <&pio0 4>;
35
36 st95hf@0{
37 reg = <0>;
38 compatible = "st,st95hf";
39 spi-max-frequency = <1000000>;
40 enable-gpio = <&pio4 0>;
41 interrupt-parent = <&pio0>;
42 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
43 };
44
45 };
