'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.

Binding for Qualcomm Atheros AR7xxx/AR9XXX MISC interrupt controller
|
|
|
|
The MISC interrupt controller is a secondary controller for lower priority
|
|
interrupt.
|
|
|
|
Required Properties:
|
|
- compatible: has to be "qca,<soctype>-cpu-intc", "qca,ar7100-misc-intc" or
|
|
"qca,<soctype>-cpu-intc", "qca,ar7240-misc-intc"
|
|
- reg: Base address and size of the controllers memory area
|
|
- interrupts: Interrupt specifier for the controllers interrupt.
|
|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Specifies the number of cells needed to encode interrupt
|
|
source, should be 1
|
|
|
|
Compatible fallback depends on the SoC. Use ar7100 for ar71xx and ar913x,
|
|
use ar7240 for all other SoCs.
|
|
|
|
Please refer to interrupts.txt in this directory for details of the common
|
|
Interrupt Controllers bindings used by client devices.
|
|
|
|
Example:
|
|
|
|
interrupt-controller@18060010 {
|
|
compatible = "qca,ar9132-misc-intc", "qca,ar7100-misc-intc";
|
|
reg = <0x18060010 0x4>;
|
|
|
|
interrupt-parent = <&cpuintc>;
|
|
interrupts = <6>;
|
|
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
};
|
|
|
|
Another example:
|
|
|
|
interrupt-controller@18060010 {
|
|
compatible = "qca,ar9331-misc-intc", qca,ar7240-misc-intc";
|
|
reg = <0x18060010 0x4>;
|
|
|
|
interrupt-parent = <&cpuintc>;
|
|
interrupts = <6>;
|
|
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
};
