Subject: Out-of-tree devfreq governor header
Content-Type: text/plain; charset="UTF-8"; format=flowed

Precedence: bulk

Hi all,

We have an out-of-tree devfreq governor which uses the "governor.h" 
header from "drivers/devfreq". The source code for the governor is 
public on CodeLinaro [1].

Currently, the driver directly includes the "governor.h" header even 
though it's not a public header. A comment at the top of "governor.h" 
says explicitly: "This header is for devfreq governors in drivers/devfreq/".

Could you please advise the best way to use this private devfreq header 
from an out-of-tree governor? Could we move the header into "include/linux"?

Thanks,
John
