'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.

Cypress I2C Touchpad
|
|
|
|
Required properties:
|
|
- compatible: must be "cypress,cyapa".
|
|
- reg: I2C address of the chip.
|
|
- interrupts: interrupt to which the chip is connected (see interrupt
|
|
binding[0]).
|
|
|
|
Optional properties:
|
|
- wakeup-source: touchpad can be used as a wakeup source.
|
|
- pinctrl-names: should be "default" (see pinctrl binding [1]).
|
|
- pinctrl-0: a phandle pointing to the pin settings for the device (see
|
|
pinctrl binding [1]).
|
|
- vcc-supply: a phandle for the regulator supplying 3.3V power.
