Subject[PATCH 0/8] GICv3 Save and Restore
Date
This patch set adds saving and restoring the GIC on v3
implementations through a devicetree flag.

The new CPU_PM state was the cleanest way to synchronize the save and
restore (that I figured out) with other PM operations since this isn't
going into any PSCI implementations (at least not in
ARM-Trusted-Firmware).

I've verified these patches on a Rockchip RK3399 platform (some
devicetree changes needed). This included turning off the power rail
for the GIC during suspend.

Derek Basehore (8):
cpu_pm: add syscore_suspend error handling
lib/iomap_copy: add __ioread64_copy()
cpu_pm: Add SYSTEM_PM state
irqchip/gic-v3: add ability to save/restore GIC/ITS state
DT/arm,gic-v3: add save-suspend-state property
irqchip/gic-v3-its: add ability to resend MAPC on resume
DT/arm,gic-v3: add resend-mapc-on-resume property
irqchip/gic-v3: add power down/up sequence
