2018-10-02usb: hub: try old enumeration scheme first for high speed devicesZeng Tao
The new scheme is required just to support legacy low and full-speed devices. For high speed devices, it will slower the enumeration speed. So in this patch we try the "old" enumeration scheme first for high speed devices, and this is what Windows does since Windows 8.

2018-10-02usb: typec: tcpm: Fix APDO PPS order checking to be based on voltageAdam Thomson
Current code mistakenly checks against max current to determine order but this should be max voltage. This commit fixes the issue so order is correctly determined, thus avoiding failure based on a higher voltage PPS APDO having a lower maximum current output, which is actually valid.

2018-10-02usbip: fix vhci_hcd controller countingMaciej Żenczykowski
Without this usbip fails on a machine with devices that lexicographically come after vhci_hcd. ie. $ ls -l /sys/devices/platform ... drwxr-xr-x. 4 root root 0 Sep 19 16:21 serial8250 -rw-r--r--. 1 root root 4096 Sep 19 23:50 uevent drwxr-xr-x. 6 root root 0 Sep 20 13:15 vhci_hcd.0 drwxr-xr-x. 4 root root 0 Sep 19 16:22 w83627hf.656 Because it detects 'w83627hf.656' as another vhci_hcd controller, and then fails to be able to talk to it. Note: this doesn't actually fix usbip's support for multiple controllers... that's still broken for other reasons ("vhci_hcd.0" is hardcoded in a string macro), but is enough to actually make it work on the above machine.

There is currently a warning when building the Kryo cpufreq driver into the kernel image: WARNING: vmlinux.o(.text+0x8aa424): Section mismatch in reference from the function qcom_cpufreq_kryo_probe() to the function .init.text:qcom_cpufreq_kryo_get_msm_id() The function qcom_cpufreq_kryo_probe() references the function __init qcom_cpufreq_kryo_get_msm_id(). This is often because qcom_cpufreq_kryo_probe lacks a __init annotation or the annotation of qcom_cpufreq_kryo_get_msm_id is wrong. Remove the '__init' annotation from qcom_cpufreq_kryo_get_msm_id so that there is no more mismatch warning. Additionally, Nick noticed that the remove function was marked as '__init' when it should really be marked as '__exit'.

This reverts commit 8ada211d0383b72878582bd312b984a9eae62b30. R-Car D3 can use OTG mode in fact. So, the commit doesn't need anymore. In other words, like other R-Car Gen3 SoCs, R-Car D3 can change the mode by using the phy-rcar-gen3-usb2 driver.

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.

2018-09-28xhci: 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.

2018-09-28xhci: Use soft retry to recover faster from transaction errorsMathias Nyman
Use soft retry to recover from a USB Transaction Errors that are caused by temporary error conditions. The USB device is not aware that the xHC has halted the endpoint, and will be waiting for another retry A Soft Retry perform additional retries and recover from an error which has caused the xHC to halt an endpoint. Soft retry has some limitations: Soft Retry attempts shall not be performed on Isoch endpoints Soft Retry attempts shall not be performed if the device is behind a TT in a HS Hub Software shall limit the number of unsuccessful Soft Retry attempts to prevent an infinite loop.
