1 * Texas Instruments TRF7970A RFID/NFC/15693 Transceiver
4 - compatible: Should be "ti,trf7970a".
5 - spi-max-frequency: Maximum SPI frequency (<= 2000000).
6 - interrupts: A single interrupt specifier.
7 - ti,enable-gpios: One or two GPIO entries used for 'EN' and 'EN2' pins on the
9 - vin-supply: Regulator for supply voltage to VIN pin
12 - pinctrl-names: Contains only one value - "default".
13 - pintctrl-0: Specifies the pin control groups used for this controller.
14 - autosuspend-delay: Specify autosuspend delay in milliseconds.
15 - irq-status-read-quirk: Specify that the trf7970a being used has the
17 - en2-rf-quirk: Specify that the trf7970a being used has the "EN2 RF"
19 - vdd-io-supply: Regulator specifying voltage for vdd-io
20 - clock-frequency: Set to specify that the input frequency to the trf7970a is 13560000Hz or 2712000…
