   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         };
