Merge tag 'usb-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB driver update from Greg KH: "Here's the big USB driver update for 3.13-rc1. It includes the usual xhci changes, EHCI updates to get the scheduling of USB transactions working better, and a raft of gadget and musb updates as well. All of this has been in linux-next for a while with no reported issues" * tag 'usb-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (305 commits) USB: Maintainers change for usb serial drivers usb: usbtest: support container id descriptor test usb: usbtest: support superspeed device capbility descriptor test usb: usbtest: support usb2 extension descriptor test usb: chipidea: only get vbus regulator for non-peripheral mode USB: ehci-atmel: add usb_clk for transition to CCF usb: cdc-wdm: ignore speed change notifications USB: cdc-wdm: support back-to-back USB_CDC_NOTIFY_RESPONSE_AVAILABLE notifications usbatm: Fix dynamic_debug / ratelimited atm_dbg and atm_rldbg macros printk: pr_debug_ratelimited: check state first to reduce "callbacks suppressed" messages usb: usbtest: support bos descriptor test for usb 3.0 USB: phy: samsung: Support multiple PHYs of same type usb: wusbcore: change WA_SEGS_MAX to a legal value usb: wusbcore: add a quirk for Alereon HWA device isoc behavior usb: wusbcore: combine multiple isoc frames in a single transfer request. usb: wusbcore: set the RPIPE wMaxPacketSize value correctly usb: chipidea: host: more enhancement when ci->hcd is NULL usb: ohci: remove ep93xx bus glue platform driver usb: usbtest: fix checkpatch warning as sizeof code style UWB: clean up attribute use by using ATTRIBUTE_GROUPS() ...
