git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb Pull USB updates from Greg KH: "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 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" * tag 'usb-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (263 commits) staging: typec: Fairchild FUSB302 Type-c chip driver staging: typec: Type-C Port Controller Interface driver (tcpci) staging: typec: USB Type-C Port Manager (tcpm) usb: host: xhci: remove #ifdef around PM functions usb: musb: don't mark of_dev_auxdata as initdata usb: misc: legousbtower: Fix buffers on stack USB: Revert "cdc-wdm: fix "out-of-sync" due to missing notifications" usb: Make sure usb/phy/of gets built-in USB: storage: e-mail update in drivers/usb/storage/unusual_devs.h usb: host: xhci: print correct command ring address usb: host: xhci: delete sp_dma_buffers for scratchpad usb: host: xhci: using correct specification chapter reference for DCBAAP xhci: switch to pci_alloc_irq_vectors usb: host: xhci-plat: set resume_quirk() for R-Car controllers usb: host: xhci-plat: add resume_quirk() usb: host: xhci-plat: enable clk in resume timing usb: host: plat: Enable xHCI plat runtime PM USB: serial: ftdi_sio: add device ID for Microsemi/Arrow SF2PLUS Dev Kit USB: serial: constify static arrays usb: fix some references for /proc/bus/usb ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "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" * tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: f7188x: Add a missing break gpio: omap: return error if requested debounce time is not possible gpio: Add ROHM BD9571MWV-M PMIC GPIO driver gpio: gpio-wcove: fix GPIO IRQ status mask gpio: DT bindings, move tca9554 from pcf857x to pca953x gpio: move tca9554 from pcf857x to pca953x gpio: arizona: Correct check whether the pin is an input gpio: Add XRA1403 DTS binding documentation dt-bindings: add exar to vendor prefixes list gpio: gpio-wcove: fix irq pending status bit width gpio: dwapb: use dwapb_read instead of readl_relaxed gpio: aspeed: Add open-source and open-drain support gpio: aspeed: Add debounce support gpio: aspeed: dt: Add optional clocks property gpio: aspeed: dt: Fix description alignment in bindings document gpio: mvebu: Add limited PWM support gpio: Use unsigned int for interrupt numbers gpio: f7188x: Add F71889A GPIO support. gpio: core: Decouple open drain/source flag with active low/high gpio: arizona: Correct handling for reading input GPIOs ...

2017-04-25USB: Revert "cdc-wdm: fix "out-of-sync" due to missing notifications"Bjørn Mork1-99/+4
This reverts commit 833415a3e781 ("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.

commit a6ff6cbf1fab ("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.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: changes for v4.12 With 51 non-merge commits, this is one of the smallest USB Gadget pull requests. Apart from your expected set of non-critical fixes, and other miscellaneous items, we have most of the changes in dwc3 (52.5%) with all other UDCs following with 34.8%. As for the actual changes, the most important of them are all the recent changes to reduce memory footprint of dwc3, bare minimum dual-role support on dwc3 and reworked endpoint count and initialization routines.

2017-04-11usb: dwc3: Add dual-role supportRoger Quadros5-4/+111
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.

2017-04-11usb: dwc3: core: make dwc3_set_mode() work properlyRoger Quadros3-38/+80
We can't have both Host and Peripheral roles active at the same time because of one detail on DWC3: it shares the same memory area for both Host and Peripheral registers. When swapping roles we must reinitialize the new role every time. Let's make sure this works for our debugfs interface.

We're going to use this member to track which role we're currently playing, that way we can more easily implement dual-role swap in upcoming patches. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

allow usb_del_gadget_udc() and usb add_gadget_udc() to be called repeatedly on the same gadget->dev structure. We need to clear the gadget->dev structure so that kobject_init() doesn't complain about already initialized object.

2017-04-11usb: dwc3: simplify ZLP handlingFelipe Balbi3-83/+59
It's much simpler to just add one extra TRB chained to previous TRB to handle ZLP. This helps us reduce pointless allocations and simplifies the code a little bit. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2017-04-11usb: dwc3: ep0: improve handling of unaligned OUT requestsFelipe Balbi3-92/+29
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. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2017-04-11usb: gadget: mv_u3d: fix error handling in mv_u3d_probe()Alexey Khoroshilov1-6/+9
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().
