1*4882a593Smuzhiyun* STMicroelectronics : NFC Transceiver ST95HF 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunST NFC Transceiver is required to attach with SPI bus. 4*4882a593SmuzhiyunST95HF node should be defined in DT as SPI slave device of SPI 5*4882a593Smuzhiyunmaster with which ST95HF transceiver is physically connected. 6*4882a593SmuzhiyunThe properties defined below are required to be the part of DT 7*4882a593Smuzhiyunto include ST95HF transceiver into the platform. 8*4882a593Smuzhiyun 9*4882a593SmuzhiyunRequired properties: 10*4882a593Smuzhiyun=================== 11*4882a593Smuzhiyun- reg: Address of SPI slave "ST95HF transceiver" on SPI master bus. 12*4882a593Smuzhiyun 13*4882a593Smuzhiyun- compatible: should be "st,st95hf" for ST95HF NFC transceiver 14*4882a593Smuzhiyun 15*4882a593Smuzhiyun- spi-max-frequency: Max. operating SPI frequency for ST95HF 16*4882a593Smuzhiyun transceiver. 17*4882a593Smuzhiyun 18*4882a593Smuzhiyun- enable-gpio: GPIO line to enable ST95HF transceiver. 19*4882a593Smuzhiyun 20*4882a593Smuzhiyun- interrupts : Standard way to define ST95HF transceiver's out 21*4882a593Smuzhiyun interrupt. 22*4882a593Smuzhiyun 23*4882a593SmuzhiyunOptional property: 24*4882a593Smuzhiyun================= 25*4882a593Smuzhiyun- st95hfvin-supply : This is an optional property. It contains a 26*4882a593Smuzhiyun phandle to ST95HF transceiver's regulator supply node in DT. 27*4882a593Smuzhiyun 28*4882a593SmuzhiyunExample: 29*4882a593Smuzhiyun======= 30*4882a593Smuzhiyunspi@9840000 { 31*4882a593Smuzhiyun reg = <0x9840000 0x110>; 32*4882a593Smuzhiyun #address-cells = <1>; 33*4882a593Smuzhiyun #size-cells = <0>; 34*4882a593Smuzhiyun cs-gpios = <&pio0 4>; 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun st95hf@0{ 37*4882a593Smuzhiyun reg = <0>; 38*4882a593Smuzhiyun compatible = "st,st95hf"; 39*4882a593Smuzhiyun spi-max-frequency = <1000000>; 40*4882a593Smuzhiyun enable-gpio = <&pio4 0>; 41*4882a593Smuzhiyun interrupt-parent = <&pio0>; 42*4882a593Smuzhiyun interrupts = <7 IRQ_TYPE_EDGE_FALLING>; 43*4882a593Smuzhiyun }; 44*4882a593Smuzhiyun 45*4882a593Smuzhiyun}; 46
