BCM2836 per-CPU interrupt controller The BCM2836 has a per-cpu interrupt controller for the timer, PMU events, and SMP IPIs. One of the CPUs may receive interrupts for the peripheral (GPU) events, which chain to the BCM2835-style interrupt controller. Required properties: - compatible: Should be "brcm,bcm2836-l1-intc" - reg: Specifies base physical address and size of the registers - interrupt-controller: Identifies the node as an interrupt controller - #interrupt-cells: Specifies the number of cells needed to encode an interrupt source. The value shall be 2 Please refer to interrupts.txt in this directory for details of the common Interrupt Controllers bindings used by client devices. The interrupt sources are as follows: 0: CNTPSIRQ 1: CNTPNSIRQ 2: CNTHPIRQ 3: CNTVIRQ 8: GPU_FAST 9: PMU_FAST Example: local_intc: local_intc { compatible = "brcm,bcm2836-l1-intc"; reg = <0x40000000 0x100>; interrupt-controller; #interrupt-cells = <2>; interrupt-parent = <&local_intc>; };
