Would appreciate being CC'd on a the non-RFC postings of this patch. 
FWIW, my use case is better described with this earlier submission:

https://lore.kernel.org/lkml/20220122035421.4086618-1-f.fainelli@gmail.com/T/#m74e4243c1af3a8d896e19b573b58f562fa09961d

It would be neat if I could leverage your driver in order to implement 
this custom "reboot powercycle" implementation. Towards that goal, we 
would likely need to specify the desired reboot "sub" operation 
alongside its PSCI SYSTEM_RESET2 reboot type argument?

Thanks!
