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 us
Exynos5250 has external PLL (XusbXTI) for USB 3.0 PHY's
ref_pad_clk. So use this clock based on availability of
gpio to power control this PLL, otherwise use internal
clock only from XXTI.

Allow dwc3 to enable auto power management only after its PHYs
are initialized so that any further PHY handling by dwc3's
runtime power management callbacks is fine.

By enabling runtime pm in this driver allows users of
xhci-plat to enter into runtime pm. This is not full
runtime pm support (AKA xhci-plat doesn't actually power
anything off when in runtime suspend mode) but,
just basic enablement.

The PHY controller can choose between ref_pad_clk (XusbXTI-external PLL),
or EXTREFCLK (XXTI-internal clock crystal) to generate the required clock.
Adding the provision for ref_pad_clk here.

Adding APIs to handle runtime power management on PHY
devices. PHY consumers may need to wake-up/suspend PHYs

Right now it doesn't handle full runtime suspend/resume
functionality. However it allows to handle PHYs' sleep
and wakeup across runtime suspend/resume.

Now that machines may select the mode of working of DWC3 (HOST only,
GADGET only or DUAL_ROLE), lets set DWC3 mode based on that
rather than fixing it to whatever DWC3 hardware says.
This way we can skip initializing Gadget/Host in case
we are using Host-only/Gadget-only mode respectively.

The current code in the dwc3 probe effectively disables runtime pm
from ever working because it calls a get() that was never put() until
device removal. Change the runtime pm code to match the standard
formula and allow runtime pm to function.

The code in these files was moved to cm*.[ch] and prm*.[ch] in the same

low-level powerdomain functions into PRM) and 4bd5259 (ARM: OMAP2/3:
clockdomain/PRM/CM: move the low-level clockdomain functions into
