This patch set introduces support for MSI(-X) in GICv2m specification,
which is implemented in some variation of GIC400.
This patch set 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 V9 includes:
* GICv2m is now adopting the new domain hierarchy, which requires
GICv2m to implements its own irq_chip and irq_domain, as a child of GIC.
GICv2m domain is intialized using the SPI base and the number of SPIs from
V2M_MSI_TYPER registers (or the override value from DT).
* Simplified GIC logic that was used to handle MSI stuff. Now the v2m
stuff is cleanly separated.
