[QUESTION]: multi-level interrupts: single node having interrupts from multiple aggregators

[LaurentiuM1234]

Hi,

Does the current multi-level interrupt architecture support a single node having interrupts from multiple aggregators?
For example, in the following scenario:

intc1: interrupt-controller@deadbeef {
    /* some properties go here */
    interrupt-controller;
    #interrupt-cells = <1>;
}

intc1_aggr1: interrupt-controller@cafebabe {
    /* some properties go here */
    interrupt-controller;
    interrupts-extended = <&intc1 19>;
}

intc1_aggr2: interrupt-controller@cafebabe {
    /* some properties go here */
    interrupt-controller;
    interrupts-extended = <&intc1 20>;
}

my_node_label_here: some-dummy-periph@some_dummy_address {
}

my_node_label_here uses interrupts from both intc1_aggr1 and intc1_aggr2. I wasn't able to get this working so before trying to make any changes I'd like to understand if there's any alternatives to be taken into consideration. Any help would be much appreciated. Thanks!

You'll need to use the interrupts-extended property for specifying the interrupts in some-dummy-periph@some_dummy_address.
