- "arm,gic-400"
+ * 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,arm1176jzf-devchip-gic"
++ "arm,arm11mp-gic"
+ "arm,cortex-a15-gic"
- "arm,arm11mp-gic"
+ "arm,cortex-a7-gic"
- "arm,arm1176jzf-devchip-gic"
++ "arm,cortex-a9-gic"
++ "arm,gic-400"
++ "arm,pl390"
+ "brcm,brahma-b15-gic"
+ "qcom,msm-8660-qgic"
+ "qcom,msm-qgic2"
+ - 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 (invalid for SPIs)
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive (invalid for SPIs).
+ 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.
+ Also note that the configurability of PPI interrupts is IMPLEMENTATION
+ DEFINED and as such not guaranteed to be present (most SoC available
+ in 2014 seem to ignore the setting of this flag and use the hardware
+ default value).
+
+ - 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 on
+ secondary GICs, or VGIC maintenance interrupt on primary GIC (see
+ below).
+
+ - cpu-offset : per-cpu offset within the distributor and cpu interface
+ regions, used when the GIC doesn't have banked registers. The offset is
+ cpu-offset * cpu-nr.
+
++- clocks : List of phandle and clock-specific pairs, one for each entry
++ in clock-names.
++- clock-names : List of names for the GIC clock input(s). Valid clock names
++ depend on the GIC variant:
++ "ic_clk" (for "arm,arm11mp-gic")
++ "PERIPHCLKEN" (for "arm,cortex-a15-gic")
++ "PERIPHCLK", "PERIPHCLKEN" (for "arm,cortex-a9-gic")
++ "clk" (for "arm,gic-400")
++ "gclk" (for "arm,pl390")
++
++- power-domains : A phandle and PM domain specifier as defined by bindings of
++ the power controller specified by phandle, used when the GIC
++ is part of a Power or Clock Domain.
++
++
+ Example:
+
+ intc: interrupt-controller@fff11000 {
+ compatible = "arm,cortex-a9-gic";
+ #interrupt-cells = <3>;
+ #address-cells = <1>;
+ interrupt-controller;
+ reg = <0xfff11000 0x1000>,
+ <0xfff10100 0x100>;
+ };
+
+
+ * GIC virtualization extensions (VGIC)
+
+ For ARM cores that support the virtualization extensions, additional
+ properties must be described (they only exist if the GIC is the
+ primary interrupt controller).
+
+ Required properties:
+
+ - reg : Additional regions specifying the base physical address and
+ size of the VGIC registers. The first additional region is the GIC
+ virtual interface control register base and size. The 2nd additional
+ region is the GIC virtual cpu interface register base and size.
+
+ - interrupts : VGIC maintenance interrupt.
+
+ Example:
+
+ interrupt-controller@2c001000 {
+ compatible = "arm,cortex-a15-gic";
+ #interrupt-cells = <3>;
+ interrupt-controller;
+ reg = <0x2c001000 0x1000>,
+ <0x2c002000 0x1000>,
+ <0x2c004000 0x2000>,
+ <0x2c006000 0x2000>;
+ interrupts = <1 9 0xf04>;
+ };
+
+
+ * GICv2m extension for MSI/MSI-x support (Optional)
+
+ Certain revisions of GIC-400 supports MSI/MSI-x via V2M register frame(s).
+ This is enabled by specifying v2m sub-node(s).
+
+ Required properties:
+
+ - compatible : The value here should contain "arm,gic-v2m-frame".
+
+ - msi-controller : Identifies the node as an MSI controller.
+
+ - reg : GICv2m MSI interface register base and size
+
+ Optional properties:
+
+ - arm,msi-base-spi : When the MSI_TYPER register contains an incorrect
+ value, this property should contain the SPI base of
+ the MSI frame, overriding the HW value.
+
+ - arm,msi-num-spis : When the MSI_TYPER register contains an incorrect
+ value, this property should contain the number of
+ SPIs assigned to the frame, overriding the HW value.
+
+ Example:
+
+ interrupt-controller@e1101000 {
+ compatible = "arm,gic-400";
+ #interrupt-cells = <3>;
+ #address-cells = <2>;
+ #size-cells = <2>;
+ interrupt-controller;
+ interrupts = <1 8 0xf04>;
+ ranges = <0 0 0 0xe1100000 0 0x100000>;
+ reg = <0x0 0xe1110000 0 0x01000>,
+ <0x0 0xe112f000 0 0x02000>,
+ <0x0 0xe1140000 0 0x10000>,
+ <0x0 0xe1160000 0 0x10000>;
+ v2m0: v2m@0x8000 {
+ compatible = "arm,gic-v2m-frame";
+ msi-controller;
+ reg = <0x0 0x80000 0 0x1000>;
+ };
+
+ ....
+
+ v2mN: v2m@0x9000 {
+ compatible = "arm,gic-v2m-frame";
+ msi-controller;
+ reg = <0x0 0x90000 0 0x1000>;
+ };
+ };
