[PATCH v4 0/5] GICv3 Save and Restore

[Derek Basehore]

A lot of changes in v2. The distributor and redistributor saving and
restoring is left to the PSCI/firmware implementation after
discussions with ARM. This reduces the line changes by a lot and
removes now unneeded patches.

Patches are verified on an RK3399 platform with pending patches in the
ARM-Trusted-Firmware project.

Just a couple minor changes in v3 to formatting.

Fixed a false ITS wedged detection due to the cmd_write and creadr
offsets not matching up on reset in v4. Also minor formatting changes.

Derek Basehore (5):
  cpu_pm: add syscore_suspend error handling
  irqchip/gic-v3-its: add ability to save/restore ITS state
  DT/arm,gic-v3-its: add reset-on-suspend property
  irqchip/gic-v3-its: add ability to resend MAPC on resume
  DT/arm,gic-v3: add collections-reset-on-suspend property
