Merge branch 'cpuidle/biglittle' into next/drivers
From Lorenzo Pieralisi:
This patch series contains:
- GIC driver update to add a method to disable the GIC CPU IF
- TC2 MCPM update to add GIC CPU disabling to suspend method
- TC2 CPU idle big.LITTLE driver
* cpuidle/biglittle:
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()
ARM: vexpress/TC2: implement PM suspend method
ARM: vexpress/TC2: basic PM support
ARM: vexpress: Add SCC to V2P-CA15_A7's device tree
ARM: vexpress/TC2: add Serial Power Controller (SPC) support
ARM: vexpress/dcscb: fix cache disabling sequences
