Subject[PATCH v3 5/5] DT/arm,gic-v3: add collections-reset-on-suspend property
Date
This boolean property for the GIC-V3-ITS enables resending the MAP
COLLECTIONS commands when resuming for when the state is reset on
suspend.

- reset-on-suspend: Boolean property. Indicates that the ITS state is
reset on suspend. The state is then saved on suspend and restored on
resume.
+- collections-reset-on-suspend : Boolean property. If the collections for the
+ ITS are stored internally instead of externally, the state will be lost if the
+ GIC loses power. Setting this enables the kernel to reset the collections
+ state on resume for this ITS node.

The main GIC node must contain the appropriate #address-cells,
#size-cells and ranges properties for the reg property of all ITS
