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. 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 V3: * Rebase to git://git.infradead.org/users/jcooper/linux.git irqchip/gic (per Jason Cooper request) * Misc fix/clean up per Mark Rutland comments * Minor Clean up in the driver/irqchip/irq-gic-v2m.c: alloc_msi_irqs() * Patch 4 is new to the series: * Add ARM64-specific version arch_setup_msi_irqs() to allow support for Multiple MSI. * Add support for Multiple MSI for GICv2m. Suravee Suthikulpanit (4): irqchip: gic: Add binding probe for ARM GIC400 irqchip: gic: Restructuring ARM GIC code irqchip: gic: Add supports for ARM GICv2m MSI(-X) irqchip: gicv2m: Add support for multiple MSI for ARM64 GICv2mOk, patch #1 applied to irqchip/urgent. Patches 2 and 3 applied to irqchip/gic with irqchip/urgent merged in. To facilitate testing/merging, I've prepared an unsigned tag for you on the irqchip/gic branch:I'm a little concerned that this is all going through for v3.17 without a {Reviewed,Acked}-by from Marc or anyone working with GIC{,v2m}.Well, that's why it's not in irqchip/core yet. ;-) It can be undone if needed.
Ah, perhaps I was a litte premature. :)

While his comments on v1 have been addressed, he has not had a chance to acknowledge the solutions. I appreciate Marc's holiday is unfortunately timed. I also have an open concern with the binding with regard to the orthogonality of GICV GICH and the MSI registers. Suravee, do you need this urgently for v3.17? I was under the impression that we wouldn't have full PCIe support by then.If Suravee is ok with it, I can drop them for now and he can resend for v3.18. Since we've worked out a way to merge it all in one window, I don't think it would hurt anything to wait.
Ok.
I'll leave these in irqchip/for-next until I hear from Suravee, then I'll drop the lot till we hear from Marc and look at the timing.
Keeping it in for-next for testing sounds like a good idea, but until we hear from Marc I wouldn't want to see this queued for mainline. So the above sounds fine to me. Cheers, Mark.
