[PATCH v2 0/4] chipidea: add basic system power management support

[Peter Chen]

Changes for v2:

Patch[2/4]: since we have already added hw_wait_phy_stable at ci_usb_phy_init,
the same delay after ci_usb_phy_init at probe is duplicated.

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.

usb: chipidea: remove the unnecessary delay after clear portsc.phcd
usb: chipidea: add hw_wait_phy_stable for getting stable status
usb: chipidea: add system power management support
usb: chipidea: imx: add system power management support
