| * 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 |
| - interrupt-parent: phandle for the interrupt gpio controller |
| - interrupts: GPIO interrupt to which the chip is connected |
| - enable-gpios: Output GPIO pin used for enabling/disabling the chip |
| - firmware-gpios: Output GPIO pin used to enter firmware download mode |
| |
| Optional SoC Specific Properties: |
| - pinctrl-names: Contains only one value - "default". |
| - pintctrl-0: Specifies the pin control groups used for this controller. |
| |
| 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 GPIO_ACTIVE_HIGH>; |
| |
| enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>; |
| firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>; |
| }; |
| }; |
