* | usb: remove redundant dependency on USB_SUPPORTMasahiro Yamada2016-08-09
| | | | | | | | | | | | | | | | | | The whole Kconfig entries of the USB subsystem are surrounded with "if USB_SUPPORT" ... "endif", so CONFIG_USB_SUPPORT=y is surely met when these two Kconfig options are visible.

* | usb: ulpi: Automatically set driver::owner with ulpi_driver_register()Stephen Boyd2016-08-09
| | | | | | | | | | | | | | | | | | | | | | | | Let's follow other driver registration functions and automatically set the driver's owner member to THIS_MODULE when ulpi_driver_register() is called. This allows ulpi driver writers to forget about this boiler plate detail and avoids common bugs in the process.

* | USB: bcma: initialize Northstar USB 3.0 controllerRafał Miłecki2016-08-09
| | | | | | | | | | | | | | | | | | It's a rather simple controller, we just need to make sure USB is powered (using GPIO pin) and reset bus core. Once this is done it's safe to register XHCI controller and let it init PHY and do its magic.

* | usb: storage: fix runtime pm issue in usb_stor_probe2Heiner Kallweit2016-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 71723f95463d "PM / runtime: print error when activating a child to unactive parent" I see the following error message: scsi host2: usb-storage 1-3:1.0 scsi host2: runtime PM trying to activate child device host2 but parent (1-3:1.0) is not active Digging into it it seems to be related to the problem described in the commit message for cd998ded5c12 "i2c: designware: Prevent runtime suspend during adapter registration" as scsi_add_host also calls device_add and after the call to device_add the parent device is suspended. Fix this by using the approach from the mentioned commit and getting the runtime pm reference before calling scsi_add_host.

* | cdc-wdm: fix "out-of-sync" due to missing notificationsBjørn Mork2016-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver enforces a strict one-to-one relationship between the received RESPONSE_AVAILABLE notifications and messages read from the device. At the same time, it will cancel the interrupt URB when there is no client holding the character device open. Many devices do not cope well with this behaviour. They maintain a FIFO queue of messages, and send notifications on a best effort basis. Messages are queued regardless of whether the notification is successful or not. So if the driver loses a single notification, which can easily happen when the interrupt URB is cancelled, then the device and driver becomes out-of-sync. New messages end up at the end of the queue, while the associated notification makes the driver read only the first message from the queue. This state is permanent from a user point of view. There is no no way to flush the device queue without resetting the device or using another driver. The problem is easy to hit with current QMI and MBIM command line tools, which typically close the character device after seeing the reply they expect. Any pending unsolicited messages from the device will then trigger the driver bug. Fix by always reading all queued messages from the device when the notification URB is first submitted. This is expected to end with an -EPIPE status when there are no more pending messages, so demote the printk associated with -EPIPE to debug level. The workaround has been tested on a large number of different MBIM and QMI devices, as well as the Ericsson F5521gw and H5321gw modems with real Device Management functions.

* | usb: dwc2: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2016-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alloc_ordered_workqueue replaces the deprecated create_singlethread_workqueue. There are multiple work items on the work queue, which require ordering. Hence, an ordered workqueue has been used. The workqueue "wq_otg" is not being used on a memory reclaim path. Hence, WQ_MEM_RECLAIM has not been set.

* | usb: ftdi-elan: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2016-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The status workqueue is involved in initializing the Uxxx and polling the Uxxx until a supported PCMCIA CardBus device is detected. It then starts the command and respond workqueues and then loads the module that handles the device, after which it just polls the Uxxx looking for card ejects. The command and respond workqueues are involved in implementing a command sequencer for communicating with the firmware on the other side of the FTDI chip in the Uxxx. These workqueues have only a single work item each and hence they do not require ordering. Also, none of the above workqueues are being used on a memory recliam path. Hence, the singlethreaded workqueues have been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. The work items have been sync cancelled because they are self-requeueing and need to wait for the in-flight work item to finish before proceeding with destruction. Hence, they have been sync cancelled in ftdi_status_cancel_work(), ftdi_command_cancel_work() and ftdi_response_cancel_work(). These functions are called in ftdi_elan_exit() to ensure that there are no pending work items while disconnecting the driver.

* | usb: misc: Add driver for usb4604Stephen Boyd2016-08-09
|/ | | | | | | | | | | | | | | This is a minimal driver to support bringing a usb4604 device from microchip out of reset and into hub mode. The usb4604 device is related to the usb3503 device, but it didn't seem close enough to warrant putting both into the same file. This patch borrows some of the usb3503 structure and trims it down to just handle the optional reset gpio and adds the i2c command to put the device into hub mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the Linux PCI core does not touch power state of PCI bridges and PCIe ports when system suspend is entered. Leaving them in D0 consumes power unnecessarily and may prevent the CPU from entering deeper C-states. With recent PCIe hardware we can power down the ports to save power given that we take into account few restrictions: - The PCIe port hardware is recent enough, starting from 2015. - Devices connected to PCIe ports are effectively in D3cold once the port is transitioned to D3 (the config space is not accessible anymore and the link may be powered down). - Devices behind the PCIe port need to be allowed to transition to D3cold and back. There is a way both drivers and userspace can forbid this. - If the device behind the PCIe port is capable of waking the system it needs to be able to do so from D3cold. This patch adds a new flag to struct pci_device called 'bridge_d3'. This flag is set and cleared by the PCI core whenever there is a change in power management state of any of the devices behind the PCIe port. When system later on is suspended we only need to check this flag and if it is true transition the port to D3 otherwise we leave it in D0. Also provide override mechanism via command line parameter "pcie_port_pm=[off|force]" that can be used to disable or enable the feature regardless of the BIOS manufacturing date.

So we can simply the sunxi musb glue by always registering its extcon notifier and relying on sunxi_musb_work() to enable vbus when in host-only mode. This also enables host- and peripheral-only mode with vbus monitoring.
