We have different opinions on this, there is no point in me reiterating it over and over, I am against the approach taken to solve this problem first in defining the bindings outside the ACPI specifications and second by acquiescing to what has been done so that it will be done over and over again. I will raise the point in the appropriate forum, it is up to Bjorn and Rafael to decide on this patch.
