* STMicroelectronics SAS. ST NCI NFC Controller
Required properties:
- compatible: Should be "st,st21nfcb-i2c" or "st,st21nfcc-i2c".
- clock-frequency: I²C work frequency.
- reg: address on the bus
- interrupts: GPIO interrupt to which the chip is connected
- reset-gpios: Output GPIO pin used to reset the ST21NFCB
Optional SoC Specific Properties:
- pinctrl-names: Contains only one value - "default".
- pintctrl-0: Specifies the pin control groups used for this controller.
- ese-present: Specifies that an ese is physically connected to the nfc
- uicc-present: Specifies that the uicc swp signal can be physically
connected to the nfc controller.
Example (for ARM-based BeagleBoard xM with ST21NFCB on I2C2):
&i2c2 {
st21nfcb: st21nfcb@8 {
compatible = "st,st21nfcb-i2c";
reg = <0x08>;
clock-frequency = <400000>;
interrupt-parent = <&gpio5>;
interrupts = <2 IRQ_TYPE_LEVEL_HIGH>;
reset-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>;
