Merge tag 'armsoc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"A week's worth of fixes for various ARM platforms. Diff wise, the
largest fix is for OMAP to deal with how GIC now registers interrupts
(irq_domain_add_legacy() -> irq_domain_add_linear() changes).
Besides this, a few more renesas platforms needed the GIC instatiation
done for legacy boards. There's also a fix that disables coherency of
mvebu due to issues, and a few other smaller fixes"
