Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver update from Kevin Hilman:
"This contains the ARM SoC related driver updates for v3.12. The only
thing this cycle are core PM updates and CPUidle support for ARM's TC2
big.LITTLE development platform"
* tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
cpuidle: big.LITTLE: vexpress-TC2 CPU idle driver
ARM: vexpress: tc2: disable GIC CPU IF in tc2_pm_suspend
drivers: irq-chip: irq-gic: introduce gic_cpu_if_down()
