f636cec559 usb: chipidea: usbmisc_imx: add .set_wakeup interface
This API is used to enable/disable usb wakeup, only imx6 series are
added, since I don't have other imx hardware on hand. Other imx users
can add their API according to reference manual after testing.

73dea4a912 usb: chipidea: usbmisc_imx: delete clock information
All imx usb controller's non core registers uses the same clock gate with
core registers, the usbmisc_imx is the library for imx glue driver, the
glue keeps clock on when it calls usbmisc_imx API to change non-core register.

Besides, we will support runtime pm in the future, it also needs to
close this clock when the usb is not in use.

Philipp Zabel also verifies it at imx6q platform, see

d5d1e1bed4 usb: chipidea: udc: return immediately if re-enable non-empty endpoint
Some gadget driver (like uac1) will try to enable endpoint again even
the ep is not empty, it will cause the ep reset again and may affect
the dTD list which has already queued.

It returns -EBUSY immediately, and indicate the endpoint is in use.
In this way, the ep's behavior will not be affected, and the gadget
driver is also notified.

4d4bac4499 usb: patches for v3.20 merge window
Here's the big pull request for Gadgets and PHYs. It's
 a total of 217 non-merge commits with pretty much everything
 being touched.
 
 The most important bits are a ton of new documentation for
 almost all usb gadget functions, a new isp1760 UDC driver,
 several improvements to the old net2280 UDC driver, and
 some minor tracepoint improvements to dwc3.
 
 Other than that, a big list of minor cleanups, smaller bugfixes
 and new features all over the place.

518ca8d932 ehci-pci: disable for Intel MID platforms (update)
This is a follow up to the previously submitted commit cefa9a31a5 (ehci-pci:
disable for Intel MID platforms).

It includes the following changes:
- table and function are renamed to reflect this is not only about ChipIdea
- ChipIdea PCI driver (ci_hdrc_pci.c) gets the comment about the table in
  ehci-pci.c
- MIPS IDs removed from the list since it was discovered and tested on Intel
  MID platforms

24c498df1c Revert "usb: chipidea: remove duplicate dev_set_drvdata for host_start"
This reverts commit 14b4099c07

It moved platform_set_drvdata(pdev, ci) before hcd is created,
and the hcd will assign itself as ci controller's drvdata during
the hcd creation function (in usb_create_shared_hcd), so it
overwrites the real ci's drvdata which we want to use.

So, if the controller is at host mode, the system suspend
API will get the wrong struct ci_hdrc pointer, and cause the
oops.

e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

21a5b579cb usb: chipidea: fix phy handling
The generic plaftorm device for ChipIdea drivers is probed by calling
ci_hdrc_probe. The device structure used is not the one of the specific
ChipIdea driver but the one of the generic ChipIdea platform device.

This results in not being able to probe the PHYs as we're not using the
right device structure. Since all ChipIdea drivers are retrieving their
PHYs in their specific driver code, this didn't impact any of them yet.

Fixes it using the right device structure (dev->parent).

 sparse or coccinelle fixes ranging from missing
 'static' to returning 0 in case of errors.
 
 More importantly, we have the removal the now
 unnecessary 'driver' argument to ->udc_stop().
 
 DWC2 learned about Dual-Role builds. Users of
 this IP can now have a single driver built for
 host and device roles.
 
 DWC3 got support for two new HW platforms: Exynos7
 and AMD.
 
 The Broadcom USB 3.0 Device Controller IP is now
 supported and so is PLX USB338x, which means DWC3
 has lost is badge as the only USB 3.0 peripheral
 IP supported on Linux.
 
 Thanks for Tony Lindgren's work, we can now have
 a distro-like kernel where all MUSB glue layers
 can be built into the same kernel (statically
 or dynamically linked) and it'll work in PIO (DMA
 will come probably on v3.20).
 
 Other than these, the usual set of cleanups and
 non-critical fixes.

This patch adds support of the PHY framework for ChipIdea drivers.
Changes are done in both the ChipIdea common code and in the drivers
accessing the PHY. This is done by adding a new PHY member in
ChipIdea's structures and by taking care of it in the code.

ef44cb4226 usb: allow to supply the PHY in the drivers when using HCD
This patch modify the generic code handling PHYs to allow them to be
supplied from the drivers. This adds checks to ensure no PHY was already
there when looking for one in the generic code. This also makes sure we
do not modify its state in the generic HCD functions, it was provided by
the driver.

19c1eac268 usb: rename phy to usb_phy in OTG
This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.

e47d92545c usb: move the OTG state from the USB PHY to the OTG structure
Before using the PHY framework instead of the USB PHY one, we need to
move the OTG state into another place, since it won't be available when
USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.

22835b807e usb: gadget: remove unnecessary 'driver' argument
now that no UDC driver relies on the extra
'driver' argument to ->udc_stop(), we can
safely remove it.

This commit is based on previous work by
Robert Baldyga <r.baldyga@samsung.com> which
can be found at [1]; however that patch turned
out to have a high probability of regressing
many UDC drivers because of a blind search & replace
s/driver/$udc->driver/ which caused the 'driver'
argument to stop_activity() to be a valid non-NULL
pointer when it should be NULL, thus causing UDCs
to mistakenly call gadget driver's ->disconnect()
callback.

9680b60ed7 usb: chipidea: Fix oops when removing the ci_hdrc module
The call of 'kfree(ci->hw_bank.regmap)' in ci_hdrc_remove() sometimes causes
a kernel oops when removing the ci_hdrc module.

Since there is no separate memory allocated for the ci->hw_bank.regmap array,
there is no need to free it.

Use the recently introduced usb_gadget_giveback_request() in favor of
direct invocation of the completion routine.

All places in drivers/usb/ matching "[-.]complete(" were replaced with a
call to usb_gadget_giveback_request(). This was compile-tested with all
ARM drivers enabled and runtime-tested for musb.

27c62c2da1 usb: chipidea: otg initialization is only needed when the gadget is supported
We have only needed to enable otg initialization when both of
below conditions are satisfied:

- The controller is otg capable
- The gadget function is enabled

If the controller is otg capable, but is host-only configuration, we do
not need to access register otgsc and do any otg operations (eg, create
otg workqueue).

This adds Vybrid VF610 SoC support. The IP is very similar to i.MX6,
however, the non-core registers are spread in two different register
