Marvell Armada 7K/8K PIC Interrupt controller
|
||||
---------------------------------------------
|
||||
|
||||
This is the Device Tree binding for the PIC, a secondary interrupt
|
||||
controller available on the Marvell Armada 7K/8K ARM64 SoCs, and
|
||||
typically connected to the GIC as the primary interrupt controller.
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "marvell,armada-8k-pic"
|
||||
- interrupt-controller: identifies the node as an interrupt controller
|
||||
- #interrupt-cells: the number of cells to define interrupts on this
|
||||
controller. Should be 1
|
||||
- reg: the register area for the PIC interrupt controller
|
||||
- interrupts: the interrupt to the primary interrupt controller,
|
||||
typically the GIC
|
||||
|
||||
Example:
|
||||
|
||||
pic: interrupt-controller@3f0100 {
|
||||
compatible = "marvell,armada-8k-pic";
|
||||
reg = <0x3f0100 0x10>;
|
||||
#interrupt-cells = <1>;
|
||||
interrupt-controller;
|
||||
interrupts = <GIC_PPI 15 IRQ_TYPE_LEVEL_HIGH>;
|
||||
};
