+description: >
+  Mbigen means: message based interrupt generator.
+
+  MBI is kind of msi interrupt only used on Non-PCI devices.
+
+  To reduce the wired interrupt number connected to GIC, Hisilicon designed
+  mbigen to collect and generate interrupt.
+
+  Non-pci devices can connect to mbigen and generate the interrupt by writing
+  ITS register.
