-+MIPS CPU interrupt controller
-+
-+On MIPS the mips_cpu_intc_init() helper can be used to initialize the 8 CPU
-+IRQs from a devicetree file and create a irq_domain for IRQ controller.
-+
-+With the irq_domain in place we can describe how the 8 IRQs are wired to the
-+platforms internal interrupt controller cascade.
-+
-+Below is an example of a platform describing the cascade inside the devicetree
-+and the code used to load it inside arch_init_irq().
-+
-+Required properties:
-+- compatible : Should be "mti,cpu-interrupt-controller"
-+
-+Example devicetree:
-+ cpu-irq: cpu-irq@0 {
-+ #address-cells = <0>;
-+
-+ interrupt-controller;
-+ #interrupt-cells = <1>;
-+
-+ compatible = "mti,cpu-interrupt-controller";
-+ };
-+
-+ intc: intc@200 {
-+ compatible = "ralink,rt2880-intc";
-+ reg = <0x200 0x100>;
-+
-+ interrupt-controller;
-+ #interrupt-cells = <1>;
-+
-+ interrupt-parent = <&cpu-irq>;
-+ interrupts = <2>;
-+ };
-+
-+
-+Example platform irq.c:
-+static struct of_device_id __initdata of_irq_ids[] = {
-+ { .compatible = "mti,cpu-interrupt-controller", .data = mips_cpu_intc_init },
-+ { .compatible = "ralink,rt2880-intc", .data = intc_of_init },
-+ {},
-+};
-+
-+void __init arch_init_irq(void)
-+{
-+ of_irq_init(of_irq_ids);
-+}
