[RFC PATCH 0/2] HSM implementation for Allwinner D1

[Samuel Holland]

This series adds a minimal working HSM implementation for the Allwinner
D1 SoC. It works with the Linux sbi_cpuidle driver. Even with canned
values for entry/exit latency, I am seeing 30-45 mW reduction in power
usage at idle.

Since this is the first HSM driver submission, there is no example to
follow. I have some questions in my commit message, and some extra
commentary in the code to explain what is going on. Comments welcome!

Regards,
Samuel
