-MIPS Global Interrupt Controller (GIC)
-
-The MIPS GIC routes external interrupts to individual VPEs and IRQ pins.
-It also supports local (per-processor) interrupts and software-generated
-interrupts which can be used as IPIs. The GIC also includes a free-running
-global timer, per-CPU count/compare timers, and a watchdog.
-
-Required properties:
-- compatible : Should be "mti,gic".
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt specifier. Should be 3.
- - The first cell is the type of interrupt, local or shared.
- See <include/dt-bindings/interrupt-controller/mips-gic.h>.
- - The second cell is the GIC interrupt number.
- - The third cell encodes the interrupt flags.
- See <include/dt-bindings/interrupt-controller/irq.h> for a list of valid
- flags.
-
-Optional properties:
-- reg : Base address and length of the GIC registers. If not present,
- the base address reported by the hardware GCR_GIC_BASE will be used.
-- mti,reserved-cpu-vectors : Specifies the list of CPU interrupt vectors
- to which the GIC may not route interrupts. Valid values are 2 - 7.
- This property is ignored if the CPU is started in EIC mode.
-- mti,reserved-ipi-vectors : Specifies the range of GIC interrupts that are
- reserved for IPIs.
- It accepts 2 values, the 1st is the starting interrupt and the 2nd is the size
- of the reserved range.
- If not specified, the driver will allocate the last 2 * number of VPEs in the
- system.
-
-Required properties for timer sub-node:
-- compatible : Should be "mti,gic-timer".
-- interrupts : Interrupt for the GIC local timer.
-
-Optional properties for timer sub-node:
-- clocks : GIC timer operating clock.
-- clock-frequency : Clock frequency at which the GIC timers operate.
-
-Note that one of clocks or clock-frequency must be specified.
-
-Example:
-
- gic: interrupt-controller@1bdc0000 {
- compatible = "mti,gic";
- reg = <0x1bdc0000 0x20000>;
-
- interrupt-controller;
- #interrupt-cells = <3>;
-
- mti,reserved-cpu-vectors = <7>;
- mti,reserved-ipi-vectors = <40 8>;
-
- timer {
- compatible = "mti,gic-timer";
- interrupts = <GIC_LOCAL 1 IRQ_TYPE_NONE>;
- clock-frequency = <50000000>;
- };
- };
-
- uart@18101400 {
- ...
- interrupt-parent = <&gic>;
- interrupts = <GIC_SHARED 24 IRQ_TYPE_LEVEL_HIGH>;
- ...
- };
