#1287770 — [PATCH v6 0/4] gicv2m: acpi: Add ACPI support for GICv2m MSI

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

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	v2m-multiframe-v6

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

Changes from V5: (https://lkml.org/lkml/2015/12/08/763)
  - Remove previous patch 3
  - Clean up based on Marc's review (patch 1.4)
  - Add Ackedb-by and Reviewed-by (Patch 1,2,3)
  - Expose single gicv2m_init() function for both OF and ACPI
    (per Marc's suggestion)
  - Remove gicv2m name from pr_info since this is no longer useful
    (in patch 3) (per Marc's suggestion)

Changes from V4: (https://lkml.org/lkml/2015/12/08/613)
  - Fix build error when not specifying CONFIG_IRQ_DOMAIN.

Changes from V3: (https://lkml.org/lkml/2015/10/21/691)
  - Merged patch 2 into 1, and got rid off pci_msi_get_fwnode()
    since only ACPI will likely use this. (per Marc suggestion)
  - Rebased to 4.4.0-rc4

Changes from V2: (https://lkml.org/lkml/2015/10/14/1010)
  - Minor clean up from Tomasz review comment in patch 6/6.

Changes from V1: (https://lkml.org/lkml/2015/10/13/859)
  - Rebase on top of Marc's patch to addng support for multiple MSI frames
    (https://lkml.org/lkml/2015/10/14/271)
  - Adding fwnode convenient functions (patch 3 and 4)

Hi Suravee,

I tested your v2m-multiframe-v6 branch with APM X-Gene 2 that has
multiple GICv2m frames and it worked.

Please feel free to add:

Suravee,

This is starting to look OK, and you should be able to quickly fix the
last patch. Now, I'm not sure how you want to get that merged.

The first patch touches both ACPI and PCI, so it would at least requires
Acks from Rafael and Bjorn (which is not cc-ed, and you may want to fix
that in your next post, adding linux-pci for a good measure). If they
are both happy with the change, I can pick up the series as a whole.

Thanks,

	M.
