Merge tag 'usb-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big set of USB and PHY driver patches for 4.17-rc1. Lots of USB typeC work happened this round, with code moving from the staging directory into the "real" part of the kernel, as well as new infrastructure being added to be able to handle the different types of "roles" that typeC requires. There is also the normal huge set of USB gadget controller and driver updates, along with XHCI changes, and a raft of other tiny fixes all over the USB tree. And the PHY driver updates are merged in here as well as they interacted with the USB drivers in some places. All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (250 commits) Revert "USB: serial: ftdi_sio: add Id for Physik Instrumente E-870" usb: musb: gadget: misplaced out of bounds check usb: chipidea: imx: Fix ULPI on imx53 usb: chipidea: imx: Cleanup ci_hdrc_imx_platform_flag usb: chipidea: usbmisc: small clean up usb: chipidea: usbmisc: evdo can be set e/o reset usb: chipidea: usbmisc: evdo is only specific to OTG port USB: serial: ftdi_sio: add Id for Physik Instrumente E-870 usb: dwc3: gadget: never call ->complete() from ->ep_queue() usb: gadget: udc: core: update usb_ep_queue() documentation usb: host: Remove the deprecated ATH79 USB host config options usb: roles: Fix return value check in intel_xhci_usb_probe() USB: gadget: f_midi: fixing a possible double-free in f_midi usb: core: Add USB_QUIRK_DELAY_CTRL_MSG to usbcore quirks usb: core: Copy parameter string correctly and remove superfluous null check USB: announce bcdDevice as well as idVendor, idProduct.

usbcore.nousb [USB] Disable the USB subsystem
+ usbcore.quirks=
+ [USB] A list of quirk entries to augment the built-in
+ usb core quirk list. List entries are separated by
+ commas. Each entry has the form
+ VendorID:ProductID:Flags. The IDs are 4-digit hex
+ numbers and Flags is a set of letters. Each letter
+ will change the built-in quirk; setting it if it is
+ clear and clearing it if it is set. The letters have
+ the following meanings:
+ a = USB_QUIRK_STRING_FETCH_255 (string
+ descriptors must not be fetched using
+ a 255-byte read);
+ b = USB_QUIRK_RESET_RESUME (device can't resume
+ correctly so reset it instead);
+ c = USB_QUIRK_NO_SET_INTF (device can't handle
+ Set-Interface requests);
+ d = USB_QUIRK_CONFIG_INTF_STRINGS (device can't
+ handle its Configuration or Interface
+ strings);
+ e = USB_QUIRK_RESET (device can't be reset
+ (e.g morph devices), don't use reset);
+ f = USB_QUIRK_HONOR_BNUMINTERFACES (device has
+ more interface descriptions than the
+ bNumInterfaces count, and can't handle
+ talking to these interfaces);
+ g = USB_QUIRK_DELAY_INIT (device needs a pause
+ during initialization, after we read
+ the device descriptor);
+ h = USB_QUIRK_LINEAR_UFRAME_INTR_BINTERVAL (For
+ high speed and super speed interrupt
+ endpoints, the USB 2.0 and USB 3.0 spec
+ require the interval in microframes (1
+ microframe = 125 microseconds) to be
+ calculated as interval = 2 ^
+ (bInterval-1).
+ Devices with this quirk report their
+ bInterval as the result of this
+ calculation instead of the exponent
+ variable used in the calculation);
+ i = USB_QUIRK_DEVICE_QUALIFIER (device can't
+ handle device_qualifier descriptor
+ requests);
+ j = USB_QUIRK_IGNORE_REMOTE_WAKEUP (device
+ generates spurious wakeup, ignore
+ remote wakeup capability);
+ k = USB_QUIRK_NO_LPM (device can't handle Link
+ Power Management);
+ l = USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL
+ (Device reports its bInterval as linear
+ frames instead of the USB 2.0
+ calculation);
+ m = USB_QUIRK_DISCONNECT_SUSPEND (Device needs
+ to be disconnected before suspend to
+ prevent spurious wakeup);
+ n = USB_QUIRK_DELAY_CTRL_MSG (Device needs a
+ pause after every control message);
+ Example: quirks=0781:5580:bk,0a5c:5834:gij
+
usbhid.mousepoll=
[USBHID] The interval which mice are to be polled at.
