-* 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
