I was wondering that, because exposing a pin to control the whole PMIC
low power mode seems to be something that should be generic enough to be
handled by the regulator framework.

In the current situation we do have a pwr_en pin that can be controlled
by a GPIO or whatever signal from the SoC.
That's very similar, at PMIC level, to the fixedregulator that allow a
GPIO binding to enable it.

Don't you think that should deserve a support in the fmwk?

Benoit
