Hi
This patch series makes the PC8 feature become part of the runtime PM feature.
They won't be 2 separate features anymore, but just one. You can find some good
arguments for this in the commit message of patch 5.
- Patch 1 is just a bikeshed that can be discarded if needed.
- Patches 2-4 do some necessary work to merge PC8 and runtime PM.
- Patch 5 actually merges the two features. It just does the minimal work
required to merge the feature and pass all the tests on the test suite.
- Patches 6-19 do many cleanups that become possible since the features got
merged. Each patch contains just a very small chunk of code, to make it
easier for reviewers (also for tracking regressions while I was developing
the code!).
I hope that with this, it will also be much easier to add runtime PM support on
other platforms. I also think I addressed many of Daniel's comments regarding
how we do the put/get calls, but there may still be something left: please tell
me if you find something!
I also didn't take care of implementing the interrupt changes suggested by
Daniel. This won't be trivial and will require its own patch series.
Thanks,
Paulo
