Hi Daniel,

Thanks for the explanation and thanks for the link, I wish I had read
it beforehand.

Unfortunately I don't have access to the cost of transitions between
states, nor do I have the time taken by each transition (which I could
have used to infer the cost). I only have the power consumption of the
different states.

I plan to find the adequate values by testing different combinations,
but it is going to take some efforts before having a second
patch. Since this patch already improves the situation by using the
vendor's values, I think it is a move in the right direction, even
though not being the most adequate values.
