* Texas Instruments TRF7970A RFID/NFC/15693 Transceiver
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: Should be "ti,trf7970a".
|
||||||
|
- spi-max-frequency: Maximum SPI frequency (<= 2000000).
|
||||||
|
- interrupt-parent: phandle of parent interrupt handler.
|
||||||
|
- interrupts: A single interrupt specifier.
|
||||||
|
- ti,enable-gpios: Two GPIO entries used for 'EN' and 'EN2' pins on the
|
||||||
|
TRF7970A.
|
||||||
|
- 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.
|
||||||
|
|
||||||
|
Example (for ARM-based BeagleBone with TRF7970A on SPI1):
|
||||||
|
|
||||||
|
&spi1 {
|
||||||
|
status = "okay";
|
||||||
|
|
||||||
|
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_LOW>,
|
||||||
|
<&gpio2 5 GPIO_ACTIVE_LOW>;
|
||||||
|
vin-supply = <&ldo3_reg>;
|
||||||
|
status = "okay";
|
||||||
|
};
|
||||||
|
};
