In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Instead of a per-device static timer variable, a spare timer "dev_timer"
is added to the musb structure for devices to use for their per-device
timer.

Update extcon for 4.15

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.

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.

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:

[<ffffff800875a430>] dwc2_hsotg_ep_disable+0x148/0x150

Then when dwc2_hsotg_ep_disable() is called, we call
kill_all_requests() which causes a bunch of the following
messages:

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.

In the earlier commit dad3f793 ("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.

Additionally Qualcomm QMP and QUSB2 PHY drivers need to

Driver currently resumes and increments pm usage_count
of its child device (dwc3 main) from its runtime_resume
handler. This requires dwc3 runtime_resume to perform
pm_runtime_put to decrement the pm usage_count. However
runtime_put from dwc3 happens for non pci drivers
(e.g. dwc3-if-simple.c) as well which results in dwc3
pm usage_count becoming negative after couple of
runtime suspend resume iterations. Fix this by
performing runtime_get/put from dwc3-pci driver only
using workqueue.

Driver powers-off PHYs and reinitializes DWC3 core and gadget on
resume. While this works fine for gadget mode but in host
mode there is not re-initialization of host stack. Also, resetting
bus as part of bus_suspend/resume is not correct which could affect
(or disconnect) connected devices.
Fix this by not reinitializing core on suspend/resume in host mode
for HOST only and OTG/drd configurations.

Enabling power on VBUS micro-usb pin is required only when passive OTG
cable is connected. Initially OTG VBUS power control was planned to be
done in charger driver. However such information is not really available
from the extcon notifications, so VBUS power control has to be done
directly in MUIC driver, which has all information about the attached
accessory.

For example SmartDock is externally powered accessory, provides OTG
(USB HOST) functionality and use VBUS pin for charging a device battery,
so the VBUS charging pump should be disabled in such case.

When going into S3 suspend, the Acer TravelMate P648-M and P648-G3
laptops immediately wake up 3-4 seconds later for no obvious reason.

Unbinding the integrated Huawei 4G LTE modem before suspend avoids
the issue, even though we are not using the modem at all (checked
from rescue.target/runlevel1). The problem also occurs when the option
and cdc-ether modem drivers aren't loaded; it reproduces just with the
base usb driver. Under Windows the system can suspend fine.

Seeking a better fix, we've tried a lot of things, including:
 - Check that the device's power/wakeup is disabled
 - Check that remote wakeup is off at the USB level
 - All the quirks in drivers/usb/core/quirks.c e.g. USB_QUIRK_RESET_RESUME,
   USB_QUIRK_RESET, USB_QUIRK_IGNORE_REMOTE_WAKEUP, USB_QUIRK_NO_LPM.

but none of that makes any difference.

There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.

Introduce a quirk to disable the port during suspend when the modem is
detected.

The modem from the P648-G3 model is:

usb_endpoint_maxp() has an inline keyword and searches for bits[10:0]
by & operation with 0x7ff. So, we can remove the duplicate & operation
with 0x7ff.

Add support to disable specific usb3 ports, it's useful when
usb3 phy is shared with PCIe or SATA, because we should disable
the corresponding usb3 port if the phy is used by PCIe or SATA.
Sometimes it's helpful to analyse and solve problems.

This is useful to find out the root cause when the Super Speed doesn't
work. Such as when the T-PHY is switched to PCIe or SATA, and affects
Super Speed function, the check will fail.
