2-----------------------------------------------
3
4Marvell SEI (System Error Interrupt) controller is an interrupt
5aggregator. It receives interrupts from several sources and aggregates
6them to a single interrupt line (an SPI) on the parent interrupt
7controller.
8
9This interrupt controller can handle up to 64 SEIs, a set comes from the
10AP and is wired while a second set comes from the CPs by the mean of
11MSIs.
12
13Required properties:
14
15- compatible: should be one of:
16 * "marvell,ap806-sei"
17- reg: SEI registers location and length.
18- interrupts: identifies the parent IRQ that will be triggered.
19- #interrupt-cells: number of cells to define an SEI wired interrupt
20 coming from the AP, should be 1. The cell is the IRQ
21 number.
22- interrupt-controller: identifies the node as an interrupt controller
23 for AP interrupts.
24- msi-controller: identifies the node as an MSI controller for the CPs
25 interrupts.

27Example:
28
29 sei: interrupt-controller@3f0200 {
30 compatible = "marvell,ap806-sei";
31 reg = <0x3f0200 0x40>;
32 interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
33 #interrupt-cells = <1>;
34 interrupt-controller;
35 msi-controller;
36 };
