This patch-series enables runtime power management on xhci-plat,
dwc3-core, dwc3-exynos as well as on samsung-usb3 type PHY.
This allows usb 3.0 host ports to be power managed at runtime.
We also turn off the PHY ref_clk PLL, which supplies reference clock
to USB3 type phy, when ports are not in use.

Based on 'usb-next' alongwith following patch series:
  [PATCH v4 00/11] usb: dwc3: PM support patchset
  http://www.mail-archive.com/linux-usb@vger.kernel.org/msg14676.html

  [PATCH v2] usb: xhci: add the suspend/resume functionality
  http://www.mail-archive.com/linux-usb@vger.kernel.org/msg14614.html

  [PATCH v6 0/2] Adding USB 3.0 DRD-phy support for exynos5250
  http://www.mail-archive.com/linux-usb@vger.kernel.org/msg15813.html

Changes from v1:
 - Adding required PHY APIs to handle runtime power management
   instead of directly twiddling with phy->dev.
 - Handling runtime power management of usb PHYs in dwc3 core
   driver instead of in any glue layer.
 - Splitting the patch "[PATCH 4/4] usb: phy: samsung: Enable runtime power management on samsung-usb"
   to required number to bifurcate functionality.

Vivek Gautam (10):
  usb: phy: Add APIs for runtime power management
  USB: dwc3: Adjust runtime pm to allow autosuspend
  usb: dwc3: Enable runtime pm only after PHYs are initialized
  usb: dwc3: Add runtime power management callbacks
  usb: dwc3: exynos: Enable runtime power management
  usb: xhci: Enable runtime pm in xhci-plat
  usb: phy: samsung: Enable runtime power management on usb3phy
  usb: phy: samsung: Add support for external reference clock
  usb: phy: samsung: Add support for PHY ref_clk gpio
  usb: phy: samsung: Add support for PHY refclk switching
