I will start looking at this series. But I would request PSCI/other
maintainers to wait until we see some comparison data before we merge.
If they are fine to merge w/o that, I am fine. As of now we have just
1-2 platforms to test(that too not so simple to get started) and the
long term support for them are questionable. Also with SDM845 supporting
PC, we have excellent opportunity to compare and conclude the results
found.
