8f28472a73 USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1.
 
 Lots of good stuff here, after many many many attempts, the kernel
 finally has a working typeC interface, many thanks to the Heikki and
 Guenter and others who have taken the time to get this merged.  It
 wasn't an easy path for them at all.
 
 There's also a staging driver that uses this new api, which is why it's
 coming in through this tree.
 
 Along with that, there's the usual huge number of changes for gadget
 drivers, xhci, and other stuff.  Johan also finally refactored pretty
 much every driver that was looking at USB endpoints to do it in a common
 way, which will help prevent any "badly-formed" devices from causing
 problems in drivers.  That too wasn't a simple task.
 
 All of these have been in linux-next for a while with no reported
 issues.

2bd8040174 This is the bulk of GPIO changes for the v4.12 kernel cycle:
Core changes
 
 - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
   This was a much discussed change. It affects use cases where people
   write drivers that might or might not be using GPIO resources.
   I have decided that this is the lesser evil right now.
 
 - Make gpiod_count() behave consistently across different hardware
   descriptions.
 
 - Fix the syntax around open drain/open source to not infer active
   high/low semantics.
 
 New drivers
 
 - A new single-register fixed-direction framework driver for hardware
   that have lines controlled by a single register that just work in
   one direction (out or in), including IRQ support.
 
 - Support the Fintek F71889A GPIO SuperIO controller.
 
 - Support the National NI 169445 MMIO GPIO.
 
 - Support for the X-Gene derivative of the DWC GPIO controller
 
 - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
 
 - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
   and replace both the Gemini and the Moxa ART custom drivers with
   this driver.
 
 Driver improvements
 
 - A whole slew of drivers have their spinlocks chaned to raw spinlocks
   as they provide irqchips, and thus we are progressing on realtime
   compliance.
 
 - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
   resources.
 
 - Support for the embedded PWM controller inside the MVEBU driver.
 
 - Debounce, open source and open drain support for the Aspeed driver.
 
 - Misc smaller fixes like spelling and syntax and whatnot.

c58d4055c0 A reasonably busy cycle for documentation this time around. There is a new
guide for user-space API documents, rather sparsely populated at the
 moment, but it's a start.  Markus improved the infrastructure for
 converting diagrams.  Mauro has converted much of the USB documentation
 over to RST.  Plus the usual set of fixes, improvements, and tweaks.

 get them.

d852ed98f6 usb: host: xhci: remove #ifdef around PM functions
The #ifdef is slightly wrong as it doesn't cover the xhci_priv_resume_quirk()
function, causing a harmless warning:

drivers/usb/host/xhci-plat.c:58:12: error: 'xhci_priv_resume_quirk' defined but not used [-Werror=unused-function]
 static int xhci_priv_resume_quirk(struct usb_hcd *hcd)

A simpler way to do this correctly is to use __maybe_unused annotations
that let the compiler silently drop the functions when there is no
reference.

This reverts commit 833415a3e7 ("cdc-wdm: fix "out-of-sync" due to
missing notifications")

There have been several reports of wdm_read returning unexpected EIO
errors with QMI devices using the qmi_wwan driver. The reporters
confirm that reverting prevents these errors. I have been unable to
reproduce the bug myself, and have no explanation to offer either. But
reverting is the safe choice here, given that the commit was an
attempt to work around a firmware problem.  Living with a firmware
problem is still better than adding driver bugs.

Here are the USB-serial updates for 4.12, including:
 
  - support for devices with up to 16 ports (e.g. some Moxa devices)
 
  - support for endpoint sanity checks in core, which allows for code sharing
    and avoids allocating resources for rejected interfaces
 
  - support for endpoint-port remapping, which allows some driver hacks to
    be removed as well as omninet to use the generic write implementation
 
  - removal of an obsolete tty open-race workaround which prevented a
    port from being opened immediately after having been registered
 
  - generic-driver support for interfaces with just a bulk-in endpoint
 
  - improved ftdi_sio event-char and latency-timer handling
 
  - improved ftdi_sio support for some broken BM chips
 
 Included are also various clean ups and a new ftdi_sio device id.
 
 All have been in linux-next with no reported issues.

ec1dafe8ec xhci: use correct flags for spin_lock_irqrestore() when setting port power
commit a6ff6cbf1f ("usb: xhci: Add helper function xhci_set_power_on().")
created a helper to control port power that needs to be called with
xhci->lock held and interrupts disabled.
It released the lock with spin_unlock_irqrestore using a new zero flag
variable instead of the original flag from spin_lock_irqsave.
This regression triggered a static checker warning about bogus flags, and
a null pointer dereference on armada-385.

Fix it by passing a pointer to the correct flags and using it instead

9840354ff4 usb: dwc3: Add dual-role support
If dr_mode is "otg" then support dual role mode of operation.
Currently this mode is only supported when an extcon handle is
present in the dwc3 device tree node. This is needed to
get the ID status events of the port.

We're using a workqueue to manage the dual-role state transitions
as the extcon notifier (dwc3_drd_notifier) is called in an atomic
context by extcon_sync() and this doesn't go well with
usb_del_gadget_udc() causing a lockdep and softirq warning.

4199c5f8bc usb: dwc3: ep0: improve handling of unaligned OUT requests
Just like we did for all other endpoint types, let's rely on a chained
TRB pointing to ep0_bounce_addr in order to align transfer size. This
will make the code simpler.

Instead of constantly recomputing how dwc and epnum relate to dep,
just pass dep as argument.

7d5e650a5f usb: dwc3: ep0: use immediate SETUP on TRB
If we pass TRB's own address on bpl/bph fields, we can get our SETUP
packet as immediate data on the TRB itself, without having to allocate
extra memory for it.

374a1020d2 usb: gadget: mv_u3d: fix error handling in mv_u3d_probe()
There are several inconsistencies in the error handling code.
1. If clk_get() fails, it goes to clk_put().
2. If pdata->phy_init() fails, it does not disable u3d->clk.
3. In case of failure after stopping u3d, it does pdata->phy_deinit()
   and clk_disable(u3d->clk) twice.
4. It ignores failures in clk_enable().

d7b2bff161 fsl_udc_core: add support for devices provided by fsl-mph-dr-of
Currently the of glue code in fsl-mph-dr-of will create the platform
device fsl-usb2-udc. As this driver should also be probed by this name,
this patch adds it to the devtypes list.

That helper can be used from our tracepoint interface with very minor
edits. Let's do so.
