* ARM Generic Interrupt Controller
ARM SMP cores are often associated with a GIC, providing per processor
interrupts (PPI), shared processor interrupts (SPI) and software
generated interrupts (SGI).
Primary GIC is attached directly to the CPU and typically has PPIs and SGIs.
Secondary GICs are cascaded into the upward interrupt controller and do not
have PPIs or SGIs.
Main node required properties:
- compatible : should be one of:
"arm,cortex-a9-gic"
"arm,arm11mp-gic"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. The type shall be a <u32> and the value shall be 3.
The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
interrupts.
The 2nd cell contains the interrupt number for the interrupt type.
SPI interrupts are in the range [0-987]. PPI interrupts are in the
range [0-15].
The 3rd cell is the flags, encoded as follows:
bits[3:0] trigger type and level flags.
1 = low-to-high edge triggered
2 = high-to-low edge triggered
4 = active high level-sensitive
8 = active low level-sensitive
bits[15:8] PPI interrupt cpu mask. Each bit corresponds to each of
the 8 possible cpus attached to the GIC. A bit set to '1' indicated
the interrupt is wired to that CPU. Only valid for PPI interrupts.
- reg : Specifies base physical address(s) and size of the GIC registers. The
first region is the GIC distributor register base and size. The 2nd region is
the GIC cpu interface register base and size.
Optional
- interrupts : Interrupt source of the parent interrupt controller. Only
present on secondary GICs.
Example:
intc: interrupt-controller@fff11000 {
compatible = "arm,cortex-a9-gic";
#interrupt-cells = <3>;
#address-cells = <1>;
interrupt-controller;
reg = <0xfff11000 0x1000>,
<0xfff10100 0x100>;
};

* with interrupt processing , the following still holds true
* however, all interrupts are treated the same regardless of
* if they are local IPI or PPI
*
* Interrupts 0-15 are IPI
* 16-31 are PPI
* (16-18 are the timers)
* 32-1020 are global
* 1021-1022 are reserved
* 1023 is "spurious" (no interrupt)
*
* A simple read from the controller will tell us the number of the
* highest priority enabled interrupt. We then just need to check
* whether it is in the valid range for an IRQ (0-1020 inclusive).
*
* Base ARM code assumes that the local (private) peripheral interrupts
* are not valid, we treat them differently, in that the privates are
* handled like normal shared interrupts with the exception that only
* one processor can register the interrupt and the handler must be
* the same for all processors.
