Subject: [V8 0/2] irqchip: gic: Introduce ARM GICv2m MSI(-X) support

From: Suravee Suthikulpanit <Suravee.Suthikulpanit@....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 v11 00/10] Support for creating generic PCI host bridges from DT
    https://lkml.org/lkml/2014/9/17/732

    [PATCH v11] Add support for PCI in AArch64
    https://lkml.org/lkml/2014/9/17/736

This patch set is rebased from:
    git://git.infradead.org/users/jcooper/linux.git irqchip/core
 
Changes in V8:
    * Minor clean up suggested by Marc
    * Acked-by: Marc Zyngier <marc.zyngier@....com>

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)
