Subject[V10 PATCH 0/2] irqchip: gic: Introduce ARM GICv2m MSI(-X) support
Date
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 patch adopt the new hierarchy irq domain, and is rebased from:
Git tree : git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git
Git branch : domain_hierarchy
Last commit: 97d4ea1f0922fb47dd1b09cd2694b7fa5b519db9

Changes in V10 includes:
* Remove the alloc_msi_irq and integrate into gicv2m_setup_msi_irq
* Clean up the error_out logic in gicv2m_init_one
* Add comments in gic_irq_domain_alloc()
* Removed v2m_list since no longer needed with the irqdomain hierachy framework
* Rename variable in gicv2m_taredown_msi_irq to be consistent with other functions
