[PATCH 0/3] phy: core: Re-work runtime PM deployment and fix an issue

From: Ulf Hansson
Date: Tue Dec 19 2017 - 16:23:03 EST

The intend of this series is to simplify the runtime PM deployment in the phy
core, but while doing that fixing a related problem for a Renesas SoC making use
of a phy. This issue was raised by Geert Uytterhoeven and Yoshihiro Shimoda, due
to a changed behaviour in the runtime PM core.

The commit in question is f8817f61e821 (PM / runtime: Drop children check from
__pm_runtime_set_status()). However, it turned out that the problem existed
already prior this change, only that the error was printed instead of giving a
WARN splat.

More details about the changes are available in each change log. For additional
background, please have look at the link below.


Ulf Hansson (3):
phy: core: Move runtime PM reference counting to the parent device
phy: core: Drop unused runtime PM APIs
phy: core: Update the runtime PM section in the docs to reflect
