[PATCH v1 0/4] ARM: keystone: pm: switch to use generic pm domains

[Grygorii Strashko]

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].
Patch 4 is added to illustrate Keystone 2 PM domains configuration in DT.

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