* NXP Semiconductors NXP NCI NFC Controllers Required properties: - compatible: Should be "nxp,nxp-nci-i2c". - clock-frequency: I²C work frequency. - reg: address on the bus - interrupts: GPIO interrupt to which the chip is connected - enable-gpios: Output GPIO pin used for enabling/disabling the chip Optional SoC Specific Properties: - pinctrl-names: Contains only one value - "default". - pintctrl-0: Specifies the pin control groups used for this controller. - firmware-gpios: Output GPIO pin used to enter firmware download mode Example (for ARM-based BeagleBone with NPC100 NFC controller on I2C2): &i2c2 { npc100: npc100@29 { compatible = "nxp,nxp-nci-i2c"; reg = <0x29>; clock-frequency = <100000>; interrupt-parent = <&gpio1>; interrupts = <29 IRQ_TYPE_LEVEL_HIGH>; enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>; firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>; }; };
