usbip: use monotonic timestamps
This gets rid of the deprecated do_gettimeofday() function in usbip.
The comment above vgadget_get_frame() mentions that it suffers
from issues with the time jumps due to suspend and settimeofday,
so I'm changing it to use ktime_get_ts64() to use monotonic times
that don't have this problem.
I couldn't tell whether we should use CLOCK_MONOTONIC or
CLOCK_MONOTONIC_RAW here, the difference being the exact rate
when correcting for NTP. I picked monotonic time since it doesn't
change the speed to the existing code and should be better
synchronized with other machines we talk to.

I can't see any reason for this, and all other drivers wrap at

usb-storage: make use of srb local variable
Commit
8b52291a0743 ("usb-storage: fix deadlock involving host lock
and scsi_done") added a local variable to usb_stor_control_thread() in
the usb-storage driver. This local variable holds the value of
us->srb, for use after the host lock has been released.
But as long as we have the value in a local variable, we may as well
use it instead of dereferencing the us pointer all over the place.
This patch makes no functional change; it just makes the code a little
shorter and a little neater.

Detailed description for this pull request:
1. Split out extcon header file for consumer and provider device
: The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect
the state/properties of external connector. Also, it notifies the
state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API
for both provider and consumer device driver. To clarify the meaning
of header file and to remove the wrong use-case on consumer device.
- include/linux/extcon-provider.h includes API for the provider device driver.
- include/linux/extcon.h includes the API for the consumer device driver.
2. Support the SmartDock accessory on extcon-max77843.c device driver
- Support the SmartDock accessory which detects following connectors
at the same time.
: USB host throught USB hub for mouse, keyboard and so on.
: MHL connector for video output.
: Charger connector for battery charging.
- It tested with Unitek Y-2165 MHL+OTG Hub Smart Phone Dock.
3. Fix the minor issue of extcon driver
- Delete the unneeded initialization in extcon-max14577.
- Make extcon_info static const in order to fix the warning.

usb: changes for v4.15 merge window
Not much going on this time around. With only 51 non-merge commits,
this was one of the smallest pull requests from the Gadget tree.
Most of the changes are in the mtu3 driver which added support for
36-bit DMA, support for USB 3.1 and support for dual-role (along with
some non-critical fixes).
The dwc2 driver got a few improvements to how we handle gadget state
tracking and also added support for STM32F7xx devices.
Other than that, we just some minor non-critical fixes and
improvements all over the place.

usb: dwc2: Fix UDC state tracking
It has been noticed that the dwc2 udc state reporting doesn't
seem to work (at least on HiKey boards). Where after the initial
setup, the sysfs /sys/class/udc/
f72c0000.usb/state file would
report "configured" no matter the state of the OTG port.
This patch adds a call so that we report to the UDC layer when
the gadget device is disconnected.
This patch does depend on the previous patch ("usb: dwc2:
Improve gadget state disconnection handling") in this patch set
in order to properly work.

usb: dwc2: Error out of dwc2_hsotg_ep_disable() if we're in host mode
We've found that while in host mode, using Android, if one runs
the command:
stop adbd
The existing usb devices being utilized in host mode are disconnected.
This is most visible with usb networking devices.
This seems to be due to adbd closing the file:
/dev/usb-ffs/adb/ep0
Which calls ffs_ep0_release() and the following backtrace:

kill_all_requests() which causes a bunch of the following

And the usb devices connected are basically hung at this point.
It seems like if we're in host mode, we probably shouldn't run
the dwc2_hostg_ep_disable logic, so this patch returns an error
in that case.
With this patch (along with the previous patch in this set), we avoid
the mismatched interrupts and connected usb devices continue to function.
I'm not sure if some other solution would be better here, but this seems
to work, so I wanted to send it out for input on what the right approach
should be.

usb: dwc2: Improve gadget state disconnection handling
In the earlier commit
dad3f793f20f ("usb: dwc2: Make sure we
disconnect the gadget state"), I was trying to fix up the
fact that we somehow weren't disconnecting the gadget state,
so that when the OTG port was plugged in the second time we
would get warnings about the state tracking being wrong.
(This seems to be due to a quirk of the HiKey board where
we do not ever get any otg interrupts, particularly the session
end detected signal. Instead we only see status change
interrupt.)
The fix there was somewhat simple, as it just made sure to
call dwc2_hsotg_disconnect() before we connected things up
in OTG mode, ensuring the state handling didn't throw errors.
But in looking at a different issue I was seeing with UDC
state handling, I realized that it would be much better
to call dwc2_hsotg_disconnect when we get the state change
signal moving to host mode.
Thus, this patch removes the earlier disconnect call I added
and moves it (and the needed locking) to the host mode
transition.

usb: dwc3: pci: Runtime resume child device from wq
Driver currently resumes and increments pm usage_count
of its child device (dwc3 main) from its runtime_resume

pm_runtime_put to decrement the pm usage_count. However
runtime_put from dwc3 happens for non pci drivers

pm usage_count becoming negative after couple of
runtime suspend resume iterations. Fix this by
