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 following patch set which implements PCI supports for ARM64:
[PATCH v10 00/10] Support for creating generic PCI host bridges from DT https://lkml.org/lkml/2014/9/8/333
[PATCH v10] Add support for PCI in AArch64 https://lkml.org/lkml/2014/9/8/325
Changes in V7: * Fix error handling logic in gicv2m_of_init() and gicv2m_init_one(). per Marc suggestions. * Restructure the patch to integrate the multi-MSI support for V2m into the patch 2/2. * Introduce "arm,gic-v2m-frame" compatible ID for the v2m DT binding. * Introduce "arm,msi-base-spi" and "arm,msi-num-spi" property in the v2m DT binding for overwriting value in MSI_TYPER register. * Add irq-gic-v2m.c: is_msi_spi_valid() to validate the SPI base and number of SPIs. * Fix various comments from Marc (Many thanks). * Add the missing CONFIG_ARM_GICV2M (per Marcin Juszkiewicz comment)
