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