Freescale Vybrid Miscellaneous System Control - Interrupt Router
|
|
|
|
The MSCM IP contains multiple sub modules, this binding describes the second
|
|
block of registers which control the interrupt router. The interrupt router
|
|
allows to configure the recipient of each peripheral interrupt. Furthermore
|
|
it controls the directed processor interrupts. The module is available in all
|
|
Vybrid SoC's but is only really useful in dual core configurations (VF6xx
|
|
which comes with a Cortex-A5/Cortex-M4 combination).
|
|
|
|
Required properties:
|
|
- compatible: "fsl,vf610-mscm-ir"
|
|
- reg: the register range of the MSCM Interrupt Router
|
|
- fsl,cpucfg: The handle to the MSCM CPU configuration node, required
|
|
to get the current CPU ID
|
|
- interrupt-controller: Identifies the node as an interrupt controller
|
|
- #interrupt-cells: Two cells, interrupt number and cells.
|
|
The hardware interrupt number according to interrupt
|
|
assignment of the interrupt router is required.
|
|
Flags get passed only when using GIC as parent. Flags
|
|
encoding as documented by the GIC bindings.
|
|
|
|
Example:
|
|
mscm_ir: interrupt-controller@40001800 {
|
|
compatible = "fsl,vf610-mscm-ir";
|
|
reg = <0x40001800 0x400>;
|
|
fsl,cpucfg = <&mscm_cpucfg>;
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
|
|
interrupt-parent = <&intc>;
|
|
}
