I don't like this split. We should move the contents of this file to the
above file.
I checked the authorship of the relevant lines and they are all except
for a small number of lines from Linaro authors (Viresh and Ulf). I have
permission from Linaro to dual license Linaro authored bindings, so it's
not a problem to move this. I can do that and you can just drop this file.
