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.
