[PATCH v3 0/5] ARM: keystone: pm: switch to use generic pm domains

[Grygorii Strashko <grygorii.strashko@ti.com>]

Hi Santosh, Kevin,

This series switches Keystone 2 PM code to use Generic PM domains
instead of PM clock domains because of the lack of DT support
for the last.
It will finally allow to enable Runtime PM for Keystone 2.

Patch 1 was reused from [1].

RFC version of patches can be found at [2].

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.
