This one looks also like something that should be part of the patch 4.
My concern is that with these separated features you are creating points
into the kernel git tree where TPS25750 is enabled, but it's not fully
functional, or even broken in scenarious like this (suspend/resume).
You can't do that unless you have some really good reason.
Since all of these add only a bit of code each, I think it would be
better to just merge these into the initial patch that enabled
TPS25750 - so I belive patch 4/14.
