* usb: gadget: Enable L1 suspend by defaultHemant Kumar2016-09-19
| | | | | | | | | | Currently L1 suspend is disabled. Superspeed capable device needs to support L1 suspend in HS/FS/LS mode. Also, add module parameter to disable L1 suspend in High speed mode.

| * usb: dwc3: Determine connection speed for HS PHYDevdutt Patnaik2016-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DP/DM linestate is needed by the QUSB2 PHY driver to configure the polarity of DP/DM transition triggers for exiting low power mode. This was previously available via the QUSB2PHY_PORT_UTMI_STATUS PHY register which is now deprecated. In order to correctly determine the interrupt polarity we need to pass the current operating speed to the QUSB2 PHY driver. The PHY driver uses mode, speed and cable connection status to determine the linestate and configure interrupt polarities for wake up. Add logic to determine operating speed for host and device mode cases. Change-Id: Iaede1269f514a314bd9717a33100f748e7753b2a Signed-off-by: Devdutt Patnaik <dpatnaik@codeaurora.org>
* | usb: pd: Add vendor defined message handlingJack Pham2016-07-25
|/ | | | | | | | | | | | | | | Add APIs to send and receive vendor defined messages (VDM) over USB PD. A handler for a standard or vendor ID (SVID) can register callbacks to be notified of reception of VDM messages. One use case is for another kernel driver, such as DisplayPort, to be able to be notified when an Alternate Mode adapter is connected to the Type-C port in order to enter modal operation. SVID handlers should maintain their own state and timer resources in order to comply with the Power Delivery Specification.

* USB: gadget: Implement COMPAT_IOCTL for ioctlsHemant Kumar2016-06-10
| | | | | | | | | | | | | | | | | 32-bit userspace calling into 64-bit kernel cause different ioctl codes to get generated. The different ioctl code gets generated because sizeof is used on mtp and accessory structures which is different for 32/64 compilation. Because of this, 64-bit kernel can never execute the right ioctl command. Implement compat_ioctl to handle such execution environment.

* usb: dwc3: Add support for gsi endpoint disable operationHemant Kumar2016-05-11
| | | | | | | | | | | | | | gsi driver does not call the gadget API usb_ep_enable() instead uses gsi ep operation call back to enable gsi ep. As a result ep->enabled flag remains clear. Later function driver calls usb_ep_disble() API from gadget framework and ep disable operation gets skipped. Fix this by adding gsi ep operation for ep disable. This makes the enable and disable ep operations both handled by gsi ep ops.

* usb: phy: Add new OTG state OTG_STATE_B_SUSPENDEDHemant Kumar2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This state is used to handle:- - Bus suspend followed by cable disconnect: pm usage count is incremented upon cable connect. Upon bus suspend, suspend interrupt kicks in otg state machine which moves device state to OTG_STATE_B_SUSPENDED from OTG_STATE_B_PERIPHERAL and decrements pm usage count. Upon cable unplug additional decrement of pm usage count is prevented. This state also takes care the handling of cable unplug followed by bus suspend interrupt. - Host initiated resume after bus suspend: Being in OTG_STATE_B_SUSPENDED after bus suspend, upon host initiated resume, wakeup interrupt kicks in otg state machine which moves device to OTG_STATE_B_PERIPHERAL state by incrementing pm usage count. - PC reboot with cable plugged in: After PC shutdown device goes to OTG_STATE_B_SUSPENDED state. After PC start power event irq thread kicks in otg state machine to move device to OTG_STATE_B_PERIPHERAL state and increments pm usage count. - Composition switch after bus suspend: dwc3_gadget_pullup() kicks in otg state machine to move device state from OTG_STATE_B_SUSPENDED to OTG_STATE_B_PERIPHERAL and increments pm usage count to prevent runtime suspend during device enumeration. Also, remove pm_runtime_set_active() which sets the PM runtime stauts as active to avoid pm_runtime_get_sync() failures which explicitly checks for runtime pm status. For example, if status is active, pm_runtime_get_sync() will just increments the counter without actually resuming the device.

* usb: gadget: f_mbim: Queue notification request upon function resumeHemant Kumar2016-03-22
| | | | | | | | | | | | | | | | | | In super speed mode if userspace issues a write after usb bus suspend usb_func_ep_queue() schedules wakeup to resume the function. After that it queues the request which fails with -ENOTSUPP. As a result no notification request queued to hw and write request gets delayed to be sent until another write request comes and queues notification request after function resume. This causes mismatch to the mbim request response. Fix this by queuing the notification request upon function resume if notify count is greater than zero. Also, drop control packet after bus suspend if remote wakeup is not supported or if ep enqueue returns error other than -EAGAIN.

* usb: gadget: Fix Missing Function Wakeup notification sending on BAM wakeupDanny Segal2016-03-22
| | | | | | | | | | | | | | | | In Super-Speed mode, when the USB core wishes to issue remote wakeup due to new data arriving on the BAM to BAM path, it needs to send Function Wakeup notification to the USB host after the USB bus is resumed. However, the sending of this notification fails when the USB core needs to wake up from low-power mode, because the low-power mode exit is done asynchronously and the sending of the Function Wakeup notification can not be done until the USB bus is resumed. This patch fixes this issue by checking whether the USB bus is suspended, and if so, the sending Function Wakeup notification is delayed until the USB bus is resumed.

* net: cdc_ncm: avoid changing RX/TX buffers on MTU changesBjørn Mork2015-12-23
| | | | | | | | | | | | | | | | | | | | | NCM buffer sizes are negotiated with the device independently of the network device MTU. The RX buffers are allocated by the usbnet framework based on the rx_urb_size value set by cdc_ncm. A single RX buffer can hold a number of MTU sized packets. The default usbnet change_mtu ndo only modifies rx_urb_size if it is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size and hard_mtu independently of each other, based on dwNtbInMaxSize and dwNtbOutMaxSize respectively. It was therefore assumed that usbnet_change_mtu() would never touch rx_urb_size. This failed to consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens to be equal. Fix by implementing an NCM specific change_mtu ndo, modifying the netdev MTU without touching the buffer size settings. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

As usual, most of the changes are in the gadget subsystem, and we removed a host controller for a device that is no longer in existance, and probably never was even made public. There is also other minor driver updates and new device ids, full details in the changelog.

Because of its size, we will only describe the big things in broad terms. Many will be happy to know that dwc3 is now almost twice as fast after some profiling and speed improvements. Also in dwc3, John Youn from Synopsys added support for their new DWC USB3.1 IP Core and the HAPS platform which can be used to validate it. A series of patches from Robert Baldyga cleaned up uses of ep->driver_data as a flag for "claimed endpoint" in favor of the new ep->claimed flag. Sudip Mukherjee fixed a ton of really old problems on the amd5536udc driver. That should make a few people happy. Heikki Krogerus worked on converting dwc3 to the unified device property interface. Together with these, there's a ton of non-critical fixes, typos and stuff like that. Signed-off-by: Felipe Balbi <balbi@ti.com>
