We have PSCI SYSTEM_OFF and SYSTEM_RESET function call emulation available when running as Guest using KVM ARM.
This patch implements system reboot and poweroff using PSCI SYSTEM_OFF and SYSTEM_RESET.
I've done a similar patch [1] which also needs binding documentation to go with it. The last version of which there is no agreement on is here [2].

Thanks, for the early warning.
I would be happy to go with your patch since you have already the device tree bindings covered.
IMHO, we should try to go ahead with existing scheme of PSCI device tree bindings for SYSTEM_OFF and SYSTEM_RESET. Later anyone can propose revised PSCI device tree bindings. Its not nice to hold off good changes just because people don't agree on the device tree bindings.

DT is an ABI. Even more for virtualization. It can't be revised without keeping the old version alive. Once it is in, it is for good, and we have support it forever. So we'd better get it right from the beginning, no matter how long it takes.
