How did you test this?
Especially on Chromebooks based on Intel Cherrytrail / Braswell
platforms, they have a painful PMIC vs. OS design solution.
+Cc: Hans, who did a lot in this area.
We disable suspend of the i2c controller for the i2c-bus
to which the PMIc is connected on these platforms, so I do not
expect this to cause any new issues.
But this is something to keep an eye on,
