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@xxxxxxx>
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)
