| 2 | --------------------------------------------- |
| 3 | |
| 4 | This is the Device Tree binding for the PIC, a secondary interrupt |
| 5 | controller available on the Marvell Armada 7K/8K ARM64 SoCs, and |
| 6 | typically connected to the GIC as the primary interrupt controller. |
| 7 | |
| 8 | Required properties: |
| 9 | - compatible: should be "marvell,armada-8k-pic" |
| 10 | - interrupt-controller: identifies the node as an interrupt controller |
| 11 | - #interrupt-cells: the number of cells to define interrupts on this |
| 12 | controller. Should be 1 |
| 13 | - reg: the register area for the PIC interrupt controller |
| 14 | - interrupts: the interrupt to the primary interrupt controller, |
| 15 | typically the GIC |
| 16 | |
| 17 | Example: |
| 18 | |
| 19 | pic: interrupt-controller@3f0100 { |
| 20 | compatible = "marvell,armada-8k-pic"; |
| 21 | reg = <0x3f0100 0x10>; |
| 22 | #interrupt-cells = <1>; |
| 23 | interrupt-controller; |
| 24 | interrupts = <GIC_PPI 15 IRQ_TYPE_LEVEL_HIGH>; |
| 25 | }; |
