title: Marvell SEI (System Error Interrupt) Controller

maintainers:

description: >
  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.
