     Marvell SEI (System Error Interrupt) Controller
     -----------------------------------------------
     
     Marvell SEI (System Error Interrupt) controller is an interrupt
     aggregator. It receives interrupts from several sources and aggregates
     them to a single interrupt line (an SPI) on the parent interrupt
     controller.
     
     This interrupt controller can handle up to 64 SEIs, a set comes from the
    AP and is wired while a second set comes from the CPs by the mean of
    MSIs.
    
    Required properties:
    
    - compatible: should be one of:
                  * "marvell,ap806-sei"
    - reg: SEI registers location and length.
    - interrupts: identifies the parent IRQ that will be triggered.
    - #interrupt-cells: number of cells to define an SEI wired interrupt
                        coming from the AP, should be 1. The cell is the IRQ
                        number.
    - interrupt-controller: identifies the node as an interrupt controller
                            for AP interrupts.
    - msi-controller: identifies the node as an MSI controller for the CPs
                      interrupts.
    
    Example:
    
            sei: interrupt-controller@3f0200 {
                    compatible = "marvell,ap806-sei";
                    reg = <0x3f0200 0x40>;
                    interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
                    #interrupt-cells = <1>;
                    interrupt-controller;
                    msi-controller;
            };
