* Texas Instruments TRF7970A RFID/NFC/15693 Transceiver Required properties: - compatible: Should be "ti,trf7970a". - spi-max-frequency: Maximum SPI frequency (<= 2000000). - interrupts: A single interrupt specifier. - ti,enable-gpios: One or two GPIO entries used for 'EN' and 'EN2' pins on the TRF7970A. EN2 is optional. - vin-supply: Regulator for supply voltage to VIN pin Optional SoC Specific Properties: - pinctrl-names: Contains only one value - "default". - pintctrl-0: Specifies the pin control groups used for this controller. - autosuspend-delay: Specify autosuspend delay in milliseconds. - irq-status-read-quirk: Specify that the trf7970a being used has the "IRQ Status Read" erratum. - en2-rf-quirk: Specify that the trf7970a being used has the "EN2 RF" erratum. - vdd-io-supply: Regulator specifying voltage for vdd-io - clock-frequency: Set to specify that the input frequency to the trf7970a is 13560000Hz or 27120000Hz Example (for ARM-based BeagleBone with TRF7970A on SPI1): &spi1 { nfc@0 { compatible = "ti,trf7970a"; reg = <0>; pinctrl-names = "default"; pinctrl-0 = <&trf7970a_default>; spi-max-frequency = <2000000>; interrupt-parent = <&gpio2>; interrupts = <14 0>; ti,enable-gpios = <&gpio2 2 GPIO_ACTIVE_HIGH>, <&gpio2 5 GPIO_ACTIVE_HIGH>; vin-supply = <&ldo3_reg>; vdd-io-supply = <&ldo2_reg>; autosuspend-delay = <30000>; irq-status-read-quirk; en2-rf-quirk; clock-frequency = <27120000>; }; };
