| * 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>; |
| }; |
| |
| }; |
