'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.

* Qualcomm Atheros AR9330 High-Speed UART
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must be "qca,ar9330-uart"
|
|
|
|
- reg: Specifies the physical base address of the controller and
|
|
the length of the memory mapped region.
|
|
|
|
- interrupts: Specifies the interrupt source of the parent interrupt
|
|
controller. The format of the interrupt specifier depends on the
|
|
parent interrupt controller.
|
|
|
|
Additional requirements:
|
|
|
|
Each UART port must have an alias correctly numbered in "aliases"
|
|
node.
|
|
|
|
Example:
|
|
|
|
aliases {
|
|
serial0 = &uart0;
|
|
};
|
|
|
|
uart0: uart@18020000 {
|
|
compatible = "qca,ar9330-uart";
|
|
reg = <0x18020000 0x14>;
|
|
|
|
interrupt-parent = <&intc>;
|
|
interrupts = <3>;
|
|
};
