regions, used when the GIC doesn't have banked registers. The offset is
cpu-offset * cpu-nr.
+- arm,routable-irqs : Total number of gic irq inputs which are not directly
+ connected from the peripherals, but are routed dynamically
+ by a crossbar/multiplexer preceding the GIC. The GIC irq
+ input line is assigned dynamically when the corresponding
+ peripheral's crossbar line is mapped.
Example:
intc: interrupt-controller@fff11000 {
#interrupt-cells = <3>;
#address-cells = <1>;
interrupt-controller;
+ arm,routable-irqs = <160>;
reg = <0xfff11000 0x1000>,
<0xfff10100 0x100>;
};
