Subject: [PATCH 0/3 V2] irqchip: gic: Introduce ARM GICv2m MSI(-X) support
Date: Wed, 2 Jul 2014 10:21:05 -0500 [thread overview]
Message-ID: <1404314468-7674-1-git-send-email-suravee.suthikulpanit@amd.com> (raw)
From: Suravee Suthikulpanit <Suravee.Suthikulpanit@amd.com>
This patch set introduces support for MSI(-X) in GICv2m specification,
which is implemented in some variation of GIC400 (e.g. gic-400+).
This depends on and has been tested with the V7 of "Add support for PCI in AArch64"
(https://lkml.org/lkml/2014/3/14/320).
Changes in V2:
Re-architect the code to:
* Use irq_chip for gicv2m instead of using the gic_chip (per Marc suggestion).
* Remove the overwriting of arch_setup_msi_irq and arch_setup_msi_irqs
(per Marc suggestion).
* Add devicetree matching for gic-400-plus for v2m stuff instread of
re-using gic-400 just to be clear.
* Misc fix/clean up per Mark Rutland and Marc Zyngier comments
