This patch set is applied to supprot the mbigen device.

Mbigen means message based interrupt generator.
It locate in ITS or out side of ITS.

In fact, mbigen is a kind of interrupt controller collects
the irq form Non-PCI devices and generate msi interrupt.

Hisilicon designed mbigen to reduce the wired interrupt
number connected to GIC.

In these patches, the interrupts from Non-PCI devices are
named as MBI to distiguish between legacy MSI interrupt from
PCI devices.

As a MSI interrupt controller, the mbigen is used as a child
domain of MSI domain just like PCI devices.

So,in order to support the mbigen interrupt controller, the
msi.c and its-gic-v3-its.c are changed.

Ma Jun (4):
  Add mbigen driver to support mbigen interrupt controller
  Change msi to support the Mbigen interrupt
  Change arm-gic-its to support the Mbigen interrupt
  dt-binding:Documents the mbigen bindings
