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.
