'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

* 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
|
|
- 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>;
|
|
};
|
|
};
