2019-08-08USB: Move wusbcore and UWB to staging as it is obsoleteGreg Kroah-Hartman
The UWB and wusbcore code is long obsolete, so let us just move the code out of the real part of the kernel and into the drivers/staging/ location with plans to remove it entirely in a few releases.

2019-08-07USB: add support for dev_groups to struct usb_device_driverGreg Kroah-Hartman
Now that the driver core supports dev_groups for individual drivers, expose that pointer to struct usb_device_driver to make it easier for USB drivers to also use it. Yes, users of usb_device_driver are much rare, but there are instances already that use custom sysfs files, so adding this support will make things easier for those drivers. usbip is one example, hubs might be another one.

2019-08-06USB: usbip: convert platform driver to use dev_groupsGreg Kroah-Hartman
Platform drivers now have the option to have the platform core create and remove any needed sysfs attribute files. So take advantage of that and do not register "by hand" any sysfs files.

2019-08-05USB: Disable USB2 LPM at shutdownKai-Heng Feng
The QCA Rome USB Bluetooth controller has several issues once LPM gets enabled: - Fails to get enumerated in coldboot. [1] - Drains more power (~ 0.2W) when the system is in S5. [2] - Disappears after a warmboot. [2] The issue happens because the device lingers at LPM L1 in S5, so device can't get enumerated even after a reboot. Disable LPM at shutdown to solve the issue.

2019-08-01usb: host: xhci-plat: Prevent an abnormally restrictive PHY init skippingMiquel Raynal
In the past, USB PHY handling has been moved in the HCD core. Some host controller drivers needing more control of the PHYs, they have been granted the freedom to handle themselves the PHY states and to prevent the HCD core to do so in commit 4e88d4c08301 ("usb: add a flag to skip PHY initialization to struct usb_hcd"). With this change, any USB host controller could set the hcd->skip_phy_initialization flag so that the HCD core would just skip the PHY initialization sequence. However, in the USB subsystem, there are currently two entirely different forms of PHY: one is called 'usb_phy' and is USB-subsystem-wide, while there is also the generic and kernel-wide 'phy' from the (recent) generic PHY framework. When the commit above was introduced, both type of PHYs where handled by the HCD core. Later, commit bc40f5341741 ("USB: core: hcd: drop support for legacy phys") removed the support for the former type of PHYs in the HCD core. These 'usb_phy' are still present though, but managed from the controller drivers only. Hence, setting the hcd->skip_phy_initialization flag just because a 'usb_phy' is initialized by a controller driver is a non-sense. For instance on Armada CP110, a 'usb_phy' is there to enable the power supply to the USB host, while there is also a COMPHY block providing SERDES lanes configuration that is referenced as a PHY from the common PHY framework. Right now, users of the xhci-plat.c driver either use a 'usb_phy' only and do not care about the attempt of generic PHY initialization within the HCD core (as there is none); or they use a single 'phy' and the code flow does not pass through the block setting hcd->skip_phy_initialization anyway. While there is not users of both PHY types at the same time, drop this limitation from the xhci-plat.c driver. Note that the tegra driver probably has the same limitation and could definitely benefit from a similar change.

Move USB PHYs to a standard arrays for Exynos EHCI/OHCI devices. This resolves the conflict between Exynos EHCI/OHCI sub-nodes and generic USB device bindings.

2019-07-30dt-bindings: switch Exynos EHCI/OHCI bindings to use array of generic PHYsMarek Szyprowski
Commit 69bec7259853 ("USB: core: let USB device know device node") added support for attaching devicetree node for USB devices. Those nodes are children of their USB host controller. However Exynos EHCI and OHCI driver bindings already define child-nodes for each physical root hub port and assigns respective PHY controller and parameters to them. This leads to the conflict. A workaround for it has been merged as commit 01d4071486fe ("usb: exynos: add workaround for the USB device bindings conflict"), but it disabled support for USB device binding for Exynos EHCI/OHCI controllers. To resolve it properly, lets move PHYs from the sub-nodes to a standard array under the 'phys' property.

These had been soaking in a branch targeting the merge window, but missed due to a regression hunt. This fixed up version has otherwise been in -next this past week with no reported issues. In order to gain confidence in the locking changes the pull also includes a debug / instrumentation patch to enable lockdep coverage for libnvdimm subsystem operations that depend on the device_lock for exclusion. As mentioned in the changelog it is a hack, but it works and documents the locking expectations of the sub-system in a way that others can use lockdep to verify.
