1Broadcom Generic Level 2 Interrupt Controller 2 3Required properties: 4 5- compatible: should be one of: 6 "brcm,hif-spi-l2-intc" or 7 "brcm,upg-aux-aon-l2-intc" or 8 "brcm,l2-intc" for latched interrupt controllers 9 should be "brcm,bcm7271-l2-intc" for level interrupt controllers 10- reg: specifies the base physical address and size of the registers 11- interrupt-controller: identifies the node as an interrupt controller 12- #interrupt-cells: specifies the number of cells needed to encode an 13 interrupt source. Should be 1. 14- interrupts: specifies the interrupt line in the interrupt-parent irq space 15 to be used for cascading 16 17Optional properties: 18 19- brcm,irq-can-wake: If present, this means the L2 controller can be used as a 20 wakeup source for system suspend/resume. 21 22Example: 23 24hif_intr2_intc: interrupt-controller@f0441000 { 25 compatible = "brcm,l2-intc"; 26 reg = <0xf0441000 0x30>; 27 interrupt-controller; 28 #interrupt-cells = <1>; 29 interrupt-parent = <&intc>; 30 interrupts = <0x0 0x20 0x0>; 31}; 32
