Comparing the data available in the downstream sources with what's there upstream, it was easy to spot some differences. This series aligns what we have upstream with what is there on the vendor kernel. The big asterisk there is that the downstream sources for SC8280XP can't always be trusted. A simple test shows that the lower idle states that were previously missing are implemented in the firmware (Linux reports no errors and enters them). HOWEVER The only cluster idle state that's been present until now (the deepest one) is now barely used if at all, as the scheduler seems to deem it inefficient or so. Hence, a request for testing and comments, especially from those who use the X13s daily or have reliable setup to measure the power usage.
