This patch series has been forked from the following patch series since
it no longer depends on the rest of the patches.

  [PATCH v4 00/10] ACPI GIC Self-probing, GICv2m and GICv3 support
  https://lkml.org/lkml/2015/7/29/234

It has been ported to use the newly introduced device fwnode_handle 
for ACPI irqdmain introduced by Marc in the following patch series:

  [PATCH v2 00/17] Divorcing irqdomain and device_node
  http://git.kernel.org/cgit/linux/kernel/git/maz/arm-platforms.git irq/irq-domain-fwnode-v2

The following git branch contains the submitted patches along with
the pre-requsite patches (mainly for ARM64 PCI support for ACPI).

  https://github.com/ssuthiku/linux.git	irq-domain-fwnode-v2-v2m-multiframe

This has been tested on AMD Seattle (Overdrive) RevB system. 

NOTE: I have not tested ACPI GICv2m multiframe support since
I don't have access to such system. Any helps are appreciated.

Thanks,
Suravee
