[PATCH 0/4] chipidea: add basic system power management support

[Peter Chen]

This patch set adds the basic system power management. For glue layer,
I only add it for imx which I am familar with it and have hardware for it.
For msm, it has pm management at its phy driver, zevio and pci has no
pm (clock & phy) information for its driver, so I leave these three
glue layer driver no change, I add these three glue layer users to
cc list, and will wait one month for comments.
