There are several problems with current power implementations:
1. Too many internal details are exposed to other blocks. Thus to interact with
power, they need to know which power framework is used(powerplay vs swsmu)
or even whether some API is implemented.
2. A lot of cross callings exist which make it hard to get a whole picture of
the code hierarchy. And that makes any code change/increment error-prone.
3. Many different types of lock are used. It is calculated there is totally
13 different locks are used within power. Some of them are even designed for
the same purpose.
To ease the problems above, this patch series try to
1. provide unified entry point for other blocks to interact with power.
2. relocate some source code piece/headers to avoid cross callings.
3. enforce a unified lock protection on those entry point APIs above.
That makes the future optimization for unnecessary power locks possible.
I only skimmed over it, but that looks really good on first glance.
But you need to have Alex take a look as well since I only have a very
high level understanding of power management.

Christian.
