Kishon Vijay Abraham I fa1dfe4abe ARM: OMAP2: MUSB: Specify omap4 has mailbox
Added has_mailbox to the musb platform data to specify that omap uses
an external mailbox (in control module) to communicate with the musb
core during device connect and disconnect.

Kishon Vijay Abraham I 36273356b2 ARM: OMAP: devices: create device for usb part of control module
A seperate driver has been added to handle the usb part of control
module. A device for the above driver is created here, using the register
address information to be used by the driver for powering on the PHY and
for writing to the mailbox.

Alan Stern 2f07607747 USB: GADGET: optionally force full-speed for net2280 UDC
This patch (as1656) adds a module parameter to the net2280 UDC driver
to force full-speed operation.  It is intended for testing purposes,
where one wants to check how well a full-speed device performs when
attached to a high-speed bus.  Without this parameter it would be
necessary to interpose a full-speed hub; otherwise the net2280 would
connect at high speed.

Alan Stern d0b4652f80 USB: altsetting overrides for usbtest
The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test.  It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them).  This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.

Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it.  But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.

Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting.  Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody.  In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.

The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.

 "It turns out that we had two crc bugs when running fsx-linux in a

  Ilya fixed a regression Liu Bo found in the balance ioctls for pausing

  Josef's orphan truncate patch fixes an obscure corruption we'd see
  during xfstests.

  Arne's patches address problems with subvolume quotas.  If the user
  destroys quota groups incorrectly the FS will refuse to mount.

  The rest are smaller fixes and plugs for memory leaks."

Lan Tianyu 192fef18d0 usb: enable usb port device's async suspend.
This patch is to set power.async_suspend for usb port in order
to allow it to be suspended and resumed asynchronously during
system sleep transitions.

The power.async_suspend flag is also set for devices that don't have
suspend or resume callbacks, because otherwise they would make the
main suspend/resume thread wait for their "asynchronous" children
(during suspend) or parents (during resume), effectively negating the
possible gains from executing these devices' suspend and resume
callbacks asynchronously.

Lan Tianyu ad493e5e58 usb: add usb port auto power off mechanism
This patch is to add usb port auto power off mechanism.
When usb device is suspending, usb core will suspend usb port and
usb port runtime pm callback will clear PORT_POWER feature to
power off port if all conditions were met. These conditions are
remote wakeup disable, pm qos NO_POWER_OFF flag clear and persist
enable. When it resumes, power on port again.

Add did_runtime_put in the struct usb_port to ensure
pm_runtime_get/put(portdev) to be called pairedly.  Set did_runtime_put
to true when call pm_runtime_put(portdev) during suspending. The
pm_runtime_get(portdev) only will be called when did_runtime_put
is set to true during resuming. Set did_runtime_put to false after
calling pm_runtime_get(portdev).

Make clear_port_feature() and hdev_to_hub() as global symbol.
Rename clear_port_feature() to usb_clear_port_feature() and
hdev_to_hub() to usb_hub_to_struct_hub().

Extend hub_port_debounce() with the fuction of debouncing to
be connected. Add two wraps: hub_port_debounce_be_connected()
and hub_port_debouce_be_stable().

Increase HUB_DEBOUNCE_TIMEOUT to 2000 because some usb ssds
needs around 1.5 or more to make the hub port status to be
connected steadily after being powered off and powered on.

We're saving some extra memory now by being a lot

 Our default HIRD threshold value was mistakenly set
 as one of the unsupported which would cause undefined
 behavior. Turns out that it broke OMAP5 ES2.0, so we're

 threshold (12).
 
 Quite a few fixes to Isochronous transfers and scatter/gather
 support from Pratyush.
 
 We're also starting to support devicetree-based probe with
 the latest changes from Kishon.
 
 The usual set of cleanups also available: converting debugfs
 regdump utility to regsets, better "compatible" strings for
 Exynos platforms and the removal of the dependency for
 Host and Gadget; now dwc3 can be compiled host-only, device-only,
 and/or Dual-Role.

Greg Kroah-Hartman 468234984f usb: musb: patches for v3.9 merge window
Mostly fixes all over which weren't urgent enough for
 the late -rc cycle.
 
 There is a Double Buffering fix for Host Mode TX,
 a dependency fix for the transceiver driver, some
 fixes to the error path and a fix for the use of
 omap_musb_maibox.
 
 Other than these fixes, there a removal duplicate
 headers from the dsps glue layer and removal of
 redundant assignments in omap2430_probe().

In order to add support for multipe PHY's of the same type, new API's
for adding PHY and getting PHY has been added. Now the binding
information for the PHY and controller should be done in platform file
using usb_bind_phy API. And for getting a PHY, the device pointer of the
USB controller and an index should be passed. Based on the binding
information that is added in the platform file, usb_get_phy_dev will return the
appropriate PHY.
Already existing API's to add and get phy by type is not removed. These
API's are deprecated and will be removed once all the platforms start to
use the new API.
