1 * STMicroelectronics SAS. ST NCI NFC Controller
4 - compatible: Should be "st,st21nfcb-spi"
5 - spi-max-frequency: Maximum SPI frequency (<= 10000000).
6 - interrupt-parent: phandle for the interrupt gpio controller
7 - interrupts: GPIO interrupt to which the chip is connected
8 - reset-gpios: Output GPIO pin used to reset the ST21NFCB
10 Optional SoC Specific Properties:
11 - pinctrl-names: Contains only one value - "default".
12 - pintctrl-0: Specifies the pin control groups used for this controller.
14 Example (for ARM-based BeagleBoard xM with ST21NFCB on SPI4):
20 st21nfcb: st21nfcb@0 {
22 compatible = "st,st21nfcb-spi";
24 clock-frequency = <4000000>;
26 interrupt-parent = <&gpio5>;
27 interrupts = <2 IRQ_TYPE_EDGE_RISING>;
29 reset-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>;
