Hi Santosh, Kevin,
I've separated these patches in standalone series as requested by
Santosh (https://lkml.org/lkml/2014/10/24/591). Also, I've kept
versioning of patches from original series and therefor this
is v4 of patches.
The patch 1 was originally introduced in  (Apr 2014) and it allows
to fill per-device list of clock from DT.
The patch 2 is small clean up needed for patch 3.
The patch 3 was created as was discussed in v2 and first introduced in v3.
Here I marked it as RFC, because I've found some disadvantages of such
approach - see comments to the patch itself.
Finally, this series is needed to enable to enable Runtime
PM for Keystone 2, but honestly I need only patch 1.
RFC version of patches can be found at .
Changes in v4:
- pm_clk_add_clk() changed to get reference on clock as
requested by Dmitry Torokhov (see v3). Now the caller has to
use clk_put() on clock pointer when done.
Changes in v3:
- handling of the case when !CONFIG_PM_RUNTIME has been
moved in PM clock framework.
Changes in v2:
- minor comments applied and rebased on top of Linux 3.18-rc1.
