2018-10-02usb: renesas_usbhs: add support for R-Car E3Yoshihiro Shimoda
This patch adds support for R-Car E3. This SoC needs to release the PLL reset by the UGCTRL register like R-Car D3. So, this patch adds a usbhs_of_match entry for this SoC with "USBHS_TYPE_RCAR_GEN3_WITH_PLL".

2018-10-02USB: gadget core: Issue ->disconnect() callback from usb_gadget_disconnect()Alan Stern
The gadget documentation doesn't state clearly whether a gadget driver's ->disconnect() callback should be invoked when the D+ pullup is turned off. Some UDC drivers do this and some don't. This patch settles the issue by making the core function usb_gadget_disconnect() issue the callback, so that UDC drivers don't need to worry about it. A description of the new behavior is added to the function's kerneldoc. Also, the patch removes a few superseded callbacks from other core routines. Future patches will remove the ->disconnect() calls from the UDC drivers that make them, as they are now unnecessary. Until all those patches are merged gadget drivers may receive extra ->disconnect() callbacks, but this should be harmless.

The original implementation from commit b504882da539 ("USB: add Freescale high-speed USB SOC device controller driver") returned NULL on failure and an allocated + initialized struct fsl_udc on success.

2018-10-02usb: gadget: fsl_udc_core: check allocation return value and cleanup on failureNicholas Mc Guire
The allocation with fsl_alloc_request() and kmalloc() were unchecked fixed this up with a NULL check and appropriate cleanup. Additionally udc->ep_qh_size was reset to 0 on failure of allocation. Similar udc->phy_mode is initially 0 (as udc_controller was allocated with kzalloc in fsl_udc_probe()) so reset it to 0 as well so that this function is side-effect free on failure. Not clear if this is necessary or sensible as fsl_udc_release() probably can not be called if fsl_udc_probe() failed - but it should not hurt.

2018-10-02usb: mtu3: disable vbus rise/fall interrupts of ltssmChunfeng Yun
The vbus rise & fall interrupts are used to enable and disable U3 function of device automatically, this cause some issues when class driver is initialized as deactivated, and will skip over software-controlled connect by pullup(), but UDC wants to keep disconnect until usb_gadget_activate() is called which calls pullup() if needed.

2018-09-28usb: core: added uevent for over-currentJon Flatley
After commit 1cbd53c8cd85 ("usb: core: introduce per-port over-current counters") usb ports expose a sysfs value 'over_current_count' to user space. This value on its own is not very useful as it requires manual polling. As a solution, fire a udev event from the usb hub device that specifies the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate the path of the usb port where the over-current event occurred and the value of 'over_current_count' in sysfs. Additionally, call sysfs_notify() so the sysfs value supports poll(). Signed-off-by: Jon Flatley <jflat@chromium.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-09-28usb: typec: fusb302: Resolve fixed power role contract setupAdam Thomson
When the controller is configured for a fixed power role (Source only or Sink only), attach does not proceed within the TCPM state machine as there is no CC event generated by this driver to update the CC line status. To rectify this, when CC is configured as Source or Sink we now make use of the hardware's automatic fixed Source or Sink toggling mechanism, which detects attaches in the same way as for DRP toggling. In this way the result of toggling is handled in the same way by the 'fusb302_handle_togdone()' function, and CC events are generated as expected for TCPM allowing a contract to be established.

2018-09-28usb: typec: fusb302: Correct spelling mistake for toggling stateAdam Thomson
There's a typo in the enum name of the 'OFF' state for toggling (TOGGLINE instead of TOGGLING). This commit resolves that trivial spelling inconsistency.

2018-09-28xhci: Avoid USB autosuspend when resuming USB2 ports.Anshuman Gupta
When USB bus host controller root hub resumes from autosuspend, it immediately tries to enter auto-suspend, but there can be a scenario when root hub is resuming its usb2 ports, in that particular case USB host controller auto suspend fails since it is busy to resuming its usb2 ports. This makes multiple failed cycles of auto-suspend until all usb2 ports of host controller root hub do not resume. This patch uses USB core framework usb_hcd_start_port_resume, usb_hcd_end_port_resume API's in order to autoresume/autosuspend root hub properly.

The XUSB firmware header is in little endian byte order, so make the fields __le32 and __le16 instead of u32 and u16 to avoid warnings from sparse when the fields are used with the endian-aware __le32_to_cpu() and __le16_to_cpu() accessors, respectively.

2018-09-28xhci-pci: allow host runtime PM as default for Intel Alpine and Titan RidgeMathias Nyman
The xhci controller on Alpine and Titan Ridge keeps the whole thunderbolt awake if the host controller is not allowed tp sleep. This is the case even if no USB devices are connected to the host. Because of this bigger impact, allow runtime pm as default for these xhci controllers in the driver.
