* 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>; |
|
}; |
|
};
