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 controller. - 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>; ese-present; uicc-present; }; }; |
