'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.

* MELFAS MIP4 Touchscreen
|
|
|
|
Required properties:
|
|
- compatible: must be "melfas,mip4_ts"
|
|
- reg: I2C slave address of the chip (0x48 or 0x34)
|
|
- interrupts: interrupt to which the chip is connected
|
|
|
|
Optional properties:
|
|
- ce-gpios: GPIO connected to the CE (chip enable) pin of the chip
|
|
|
|
Example:
|
|
i2c@00000000 {
|
|
touchscreen: melfas_mip4@48 {
|
|
compatible = "melfas,mip4_ts";
|
|
reg = <0x48>;
|
|
interrupt-parent = <&gpio>;
|
|
interrupts = <0 IRQ_TYPE_EDGE_FALLING>;
|
|
ce-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
|
|
};
|
|
};
