Taken from Paul Burton MIPS repo with minor changes from Chao-ying Fu.
Tested with 64r6el_defconfig on Boston board in 2 cluster/2 VPU and
1 cluster/4 VPU configurations.

v3:
 - Add Reviewed-by: Jiaxun Yang <jiaxun.yang@flygoat.com> for the patch 02/12.
 - Add the changes requested by Marc Zyngier for the 3/12 patch.
 - Remove the patch 11/12 (a consequence of a discussion between Jiaxun Yang
   and Marc Zyngier.
 - Re-base onto the master branch, with no functionality impact.

v2:
 - Apply correct Signed-off-by to avoid confusion.

Chao-ying Fu (1):
  irqchip: mips-gic: Setup defaults in each cluster

Paul Burton (10):
  MIPS: CPS: Add a couple of multi-cluster utility functions
  MIPS: GIC: Generate redirect block accessors
  irqchip: mips-gic: Introduce for_each_online_cpu_gic()
  irqchip: mips-gic: Support multi-cluster in for_each_online_cpu_gic()
  irqchip: mips-gic: Multi-cluster support
  clocksource: mips-gic-timer: Always use cluster 0 counter as
    clocksource
  clocksource: mips-gic-timer: Enable counter when CPUs start
  MIPS: pm-cps: Use per-CPU variables as per-CPU, not per-core
  MIPS: CPS: Introduce struct cluster_boot_config
  MIPS: CPS: Boot CPUs in secondary clusters
