-+* ARM Generic Interrupt Controller, version 3
-+
-+AArch64 SMP cores are often associated with a GICv3, providing Private
-+Peripheral Interrupts (PPI), Shared Peripheral Interrupts (SPI),
-+Software Generated Interrupts (SGI), and Locality-specific Peripheral
-+Interrupts (LPI).
-+
-+Main node required properties:
-+
-+- compatible : should at least contain "arm,gic-v3".
-+- interrupt-controller : Identifies the node as an interrupt controller
-+- #interrupt-cells : Specifies the number of cells needed to encode an
-+ interrupt source. Must be a single cell with a value of at least 3.
-+
-+ The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
-+ interrupts. Other values are reserved for future use.
-+
-+ 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 = edge triggered
-+ 4 = level triggered
-+
-+ Cells 4 and beyond are reserved for future use. When the 1st cell
-+ has a value of 0 or 1, cells 4 and beyond act as padding, and may be
-+ ignored. It is recommended that padding cells have a value of 0.
-+
-+- reg : Specifies base physical address(s) and size of the GIC
-+ registers, in the following order:
-+ - GIC Distributor interface (GICD)
-+ - GIC Redistributors (GICR), one range per redistributor region
-+ - GIC CPU interface (GICC)
-+ - GIC Hypervisor interface (GICH)
-+ - GIC Virtual CPU interface (GICV)
-+
-+ GICC, GICH and GICV are optional.
-+
-+- interrupts : Interrupt source of the VGIC maintenance interrupt.
-+
-+Optional
-+
-+- redistributor-stride : If using padding pages, specifies the stride
-+ of consecutive redistributors. Must be a multiple of 64kB.
-+
-+- #redistributor-regions: The number of independent contiguous regions
-+ occupied by the redistributors. Required if more than one such
-+ region is present.
-+
-+Examples:
-+
-+ gic: interrupt-controller@2cf00000 {
-+ compatible = "arm,gic-v3";
-+ #interrupt-cells = <3>;
-+ interrupt-controller;
-+ reg = <0x0 0x2f000000 0 0x10000>, // GICD
-+ <0x0 0x2f100000 0 0x200000>, // GICR
-+ <0x0 0x2c000000 0 0x2000>, // GICC
-+ <0x0 0x2c010000 0 0x2000>, // GICH
-+ <0x0 0x2c020000 0 0x2000>; // GICV
-+ interrupts = <1 9 4>;
-+ };
-+
-+ gic: interrupt-controller@2c010000 {
-+ compatible = "arm,gic-v3";
-+ #interrupt-cells = <3>;
-+ interrupt-controller;
-+ redistributor-stride = <0x0 0x40000>; // 256kB stride
-+ #redistributor-regions = <2>;
-+ reg = <0x0 0x2c010000 0 0x10000>, // GICD
-+ <0x0 0x2d000000 0 0x800000>, // GICR 1: CPUs 0-31
-+ <0x0 0x2e000000 0 0x800000>; // GICR 2: CPUs 32-63
-+ <0x0 0x2c040000 0 0x2000>, // GICC
-+ <0x0 0x2c060000 0 0x2000>, // GICH
